Ethics approaches EssayEthics approaches BY tealx021 Ethics in colloquy After reading about the ethical considerations considering social and group communication, there are many similarities. The two differ in the sense of size. This leads to more considerations in the larger of the two, group communication, where there may be many different interpersonal relationships in spite of appearance the undersize group. However, for this analysis, like the book, I will focus on ethical considerations of the miniscule group as a whole. Interpersonal relationships are comical in themselves, as each one is different han the next. One study ethical consideration in this context is fairness. When people are interdependent, or share mutuality, there are almost always issues of fairness or nicety that arise. These two issues are most commonly based off of individuals feelings and relational satisfaction. In our culture, this sense of Justice or fairness tush be attributed to the distr ibution of rewards in proportion to each partners contributions. Relationships are often times weighed on costs and rewards. When this cost-reward system is unbalanced in relationships, we often see issues rise.Another major consideration in interpersonal relationships is privacy and autonomy, or openness and closeness. In communication, this comes dget to self- disclosure. Issues can arise if one partner in the relationship is disclosing besides much or too little about themselves, and there is an unbalance between the two relational partners. One major issue in relationships is Jealousy, which can stem from any of these ethical considerations. In small-group communication, there are a few unique ethical considerations that arise. One major issue in small groups is groupthink.Groupthink is the practice of thinking or making decisions as a group in a way that discourages creativity or individual responsibility. Another unique ethical consideration is issues that involve symbolic c onvergence at bottom in-groups and out- groups. Symbolic convergence can create or develop stereotypes or exclusion within and outside a small group setting. Small-group and interpersonal relationships do also share ethical issues in communication. One of these is the issue of responsibility, which can be comprise as individual responsibility or the other affects responsibility of the whole relationship, and each one.In small-groups, individual responsibility can be hampered by groupthink or Symbolic convergence. In interpersonal relationships, individual responsibility can be hampered by lack of fairness, or lack of interdependence based on self-disclosure. overmuch or this is based on context, but interpersonal and small group communication share these same ethical considerations. Many of these ethical issues surrounding interpersonal communication can be channeled well through dialogical ethics.Dialogical ethics involves approaching decisions by considering attitudes and behav iors, and illingness or ability of each participant to surrender ones self-interest. This involves having an open mind, and backwash you and the relational partner as equals, almost putting yourself in the other persons shoes, setting aside your perceptual interpersonal relationships. I can attribute this to my own experience, as I feel many of the arguments I have with friends or family members would be solved if we each put ourselves in each others shoes. A practised approach to small-group communication is the virtue ethics approach.This approach puts a lot of emphasis on character, and oesnt put a set of rules in place that could potentially cause ethical issues involved in groupthink or stereotypes. This approach would hold people accountable based on character, and would promote creativity and good ideas within a small group. In my own experience in small-groups, everything comes down to virtue, including responsibility, prudence, etc. Many issues could be solved with this a pproach in a small group context. Both mentioned approaches would fit well in both interpersonal and group relationships, but I feel that I have placed them in their best-fit places.

Day Dreaming EssayI hit always dreamed of the perfect pass, the perfect place to go. As I have average returned from that very location, I am excited to share the experience with incessantlyyone. I am sure that you, too, will want to visit this place where only your madest dreams could compare. sm only-arm shopping at a local grocery store I noticed an entry box for a empty, all expenses paid getaway. I have always wanted a dream vacation, but without harnessing the term and the extra money, that was exactly what it would always be, a dream. The entry form said it was a getaway, not a vacation. So what was the difference?As I read the small print on the entry form I expected to find the catch that most of these offers have. I was surprised to find no catch. No salesman would make. No mass marketing e-mails would invade my e-mail box. The entry form barely stated that the winner would receive an all-expenses paid getaway. I entered the drawing with thoughts of getting away from the daily grind. As I leave the store with my few bags of groceries, I found myself wondering where this getaway was. The entry never said anything about the location. If I were to win, I hoped that it would be someplace warm.I let my thoughts run wild as I made the drive home. I was amazed at how good I felt vindicatory thinking about the perfect vacation. only too briefly my thoughts returned to real life and what was. During the neighboring month, after what seemed like the longest day ever, I arrived home to find a letter in the mailbox stating that I had won the all-expenses-paid getaway. My family has always called me lucky, but I have never been this lucky. There had to be a catch. As I sat voltaic pile to read the letter I felt just absolutely exhausted. I recseamed on the sofa and continued reading the award letter. Before I knew it I had dozed off.A short fourth dimension later I find myself driving to the airport. I was ushered to a very large private Le er Jet. I was stop in my tracks the moment I stepped through the entrance to the aircraft. I was amazed at the comfort level of the interior. The seats were overstuffed, soft, tan leather. There were perfectly displace tables and couches. The excitement of a real getaway was truly setting in. Strange as it was, I was not worried about the destination. The letter said to masses a small bag of only the bare necessities, so I packed two large pieces of luggage with eachthing I could think of that I big businessman need on this getaway.I was greeted by a very lovely lady, and as she showed me to my seat for the flight, I was told that once we were airborne that I could feel free to wander about the jet. As I sat in the overstuffed seat I felt my body relax. My mind tardily let go of all thoughts of my daily life and stresses. Take off was barely perceptible. I glanced out of what seemed to be a large window for an aircraft and watched the world I knew slowly disappear into the dist ance. I relaxed and closed my eyes. As the jet drifted off into the blue sky, I too drifted off. I batchnot tell you how long we were in flight as if in a dream I realized that we had landed.The landing strip was a beautiful field of grass. The outer edge of the landing strip was lined with the most beautiful green trees I had ever seen. As I reached the exit door of the jet, I saw only beauty. I didnt shaft where I was, but I really didnt care at that point. There was a play cart waiting for me at the bottom of the stairs. The number one wood was a very handsome young man. After a brief introduction he drove me to a very inviting bungalow and told me that this was where I would be staying during my visit. The bungalow had a well-appointed, covered, raised front gild area before the entrance.The view was more than I had ever hoped for. The oversized bungalow was everything I had ever dreamed of the furnishings were made to order from my very own wish list. The colors of the dec or were inviting yet calming. Not a wish or expectation had been left out. The rooms were such(prenominal) larger than I thought they would be. My luggage had already been delivered and as I began to put things in the closet and drawers, I found that my every need had already been provided for. There were clothes in the closet that were just my size and I could clearly see that they were made for a location just as this.I could not remember a time that I had felt so comfortable and relaxed. On the desk I found a booklet explaining that anything I could ever want to do, experience, purchase or eat was only a thought away. I decided to sit on the front deck and just take it all in. On the table outside next to a lovely chaise lounge was a bottle of my favorite beverage. I smiled as I sat and sipped the cool drink. I hadnt eaten all day and thoughts of what I would like to eat became clear. Just then a golf cart rolled up to the bungalow and a silver dinning tray was delivered to the outside table. The young waiter said nothing and left.The meal was exquisite. Never before had I tasted food so flavorful. Here I was on vacation and so satisfied to stay right here, relaxed. No sooner than I began to anticipate the sundown, it began. The sunset was anything but short lived. The colors were radiant. The entire scene, with all the colors, the mountains in the distance, the trees, all seemed to soak into my soul. It was just absolutely breathtaking. I really did not want to call it a day, but the thoughts of a limitless tomorrow made it easy to retire to the exquisite bedroom of the bungalow and stretch out on the elevated bed.I dosed off to sleep with the sound of a gentle breeze through the trees and the distant sound of small waves lapping against a beach. The next morning as I stared into the mirror, after my glorious shower, I found that my own reflection seemed much younger. I felt so alive and reenergize I decided to visit the small town, not too far from th e Bungalow, that the brochure said would be a delight. As I entered the colorful little community, I noticed several(prenominal) small store fronts and shops that offered for sale anything a person could want.As I made my first purchase, I was very surprised when the sales person refused my cash I tried to hand him. The sales person, seeing my shock, informed me that cash was only a temporary illusion as were all tangible treasures that most people cling to. Furthermore, I was informed that I would find, in my wallet, just enough cash to purchase anything I may want, however, I would not need it. As I continued to visit the remaining shops, I was delighted each time I wanted to make a purchase, to find just enough cash in my wallet, but the cashiers would not accept any of it.The next several days brought a joyous time of swimming in the warm crystal blue waters of a secluded lake that was like a lagoon off the coast of Australia, sunning on a sensational beach, and hiking some of t he most profound and beautiful mountains I have ever had the pleasure to see. The food had more than met my every expectation. Sleep had never been so satisfying. Every morning I was awakened by a delightful, brilliant sunrise and every evening was blissfully serene. I knew that all too soon my short getaway would have to come to an end.I chose to spend the last day of this wonderful vacation on the glorious beach I had visited several times. I swam freely in the warm water and snorkeled the coral reef where I was met with a burst of colorful coral and stunning little fish. popular opinion somewhat exhausted for the first time during my stay, I decided to relax on the soft white sand and soon fell asleep. Somewhere in that sweet spot just before wakefulness, I felt something spook on my foot and there was a phone ringing and the obnoxious perturbation of traffic. It surely must be a dream right? The thing rawling on my foot brought me to full consciousness. In a flash my dream v acation was over. I awoke to find myself still reclined on the sofa, letter in hand, telling me that my dream vacation was just that, only a dream, and out of the corner of my eye, crawling across the floor, I see the spider that brought my dream vacation to an end. You may be wondering how difficult it was to return to the reality of daily life. I must tell you that it was not all that hard because I know that I or anyone can return to this refreshing location in a event of moments.You need only let your mind drift to where it really wants to be. Daydreaming is easy and has also been touted as good for you. A deep daydream can easily turn into a dream. An article from QualityHealth. com states that recent research conducted at the University of British Columbia in Canada reveals that not only is daydreaming extremely common (experts say we spend one-third of our lives doing it), but its actually healthy. It turns out that when we let our minds wander, numerous areas of the brain are activated, more than were previously thought. And were not even witting were doing it.In this study, scientists placed subjects inside a special scanner and had them perform a routine task. Their attentiveness was gauged using brain scans, their performance on the task, and reports by subjects themselves. Not only did the parts of the subjects brains responsible for easy mental tasks activate, but so did the so-called executive network responsible for processing more involved thoughts and problems. What does this mean? When you put aside that tough essay after working on it for several hours in order to sit on your porch and stare at the flowers, it doesnt mean youre lazy.It means your brain is smart enough to recognize that switching to a more mundane activity allows complex thought to take place. By letting your mind wander, youre allowing it to hit on the solutions to problems that may have eluded you before. In fact, many creative people claim that they get their best idea s while doing something routine, such as taking a shower or going for a run. And some of the smartest kids in school may spend part of their classroom time doodling or staring out the window. Teachers or bosses may not approve of your daydreaming, but it is generally a healthy thing.Of course, if daydreaming takes up so much of your time that youre having trouble getting even basic chores completed, you probably should learn to focus a little more. Otherwise, dont worry about those mental time-outs that reenergize and refresh you for the tasks at hand. So, as you can see, you can go anywhere you want, do anything you want, see anything you want, touch, feel, or taste anything you can dream up. This can be done in a matter of minutes or if you have the time, you can spend hours at any location of your choice, in a daydream.

The General Information For Anti Globalization

The General Information For Anti GlobalizationAnti-Globalization was defended as a belief sh atomic number 18d by various semipolitical groups that people must oppose globalization (=the process of making something such as a business operate in different countries around the world) because of sorry effects it has on people, especi entirelyy in developing countries, and because of the damage it does to the environment the Longman Dictionary of Contemporary English Advanced Learners.Almost the anti-globalization activities ar spontaneous, the people whose good was affected stood up then performed the anti-globalization activities such as demonstration, ask for relieve In fact, the activities which are opposite to globalization finish be divided into 2 groups Anti-Globalization and Alter-Globalization.The anti-globalization group directly opposes to the globalization activities they think that the movement of people over the frontier must be controlled strictly explorer other coun trys natural resources and adult male resources are not permitted. This group argued that biodiversity and natural resources good deal be damaged permanently and mainly call for democratic representation, advancement of human rights and more egalitarian states.The targets of this group are the World Bank (WB), International Monetary Fund (IMF), the Organization for Economic Co-operation and Development (OECD) and the World Trade Organization (WTO) and free avocation treaties like the North American Free Trade under baseing (NAFTA), Free Trade Area of the Americas (FTAA), the Multilateral Agreement on Investment (MAI) and the General Agreement on Trade in Services (GATS).Alter-globalization is the name of a affectionate movement that supports global cooperation and interaction, but which opposes the negative effects of economic globalization, feeling that it oft works to the detriment of, or does not adequately promote, human values such as environmental and climate protection, economic justice, labor protection, protection of innate cultures and human rights. WikipediaThe different between anti-globalization and alter-globalization is anti-globalization against any kinds of globalization but the alter-globalization just mentioned about human rights, the environment, national sovereignty, and cultural diversity and so on.There are 2 popular forums for anti globalization World Social Forum and World Economic Forum.Chapter 2 Why anti-globalization cool it exist?To analyst the reverses of globalization, we think on three objects that the globalization affected to topical anaesthetic anesthetic companies, local state, and the local economic.Firstly, the local firmsWhen the nation open to globalization too soon, and too sudden, the local firms had not prepare enough to face with the competitive of over sea corporations leave behind go to bankruptcy easily. It is easy to find the example for Chuong Duong companySecondly, the local populationIf the global ization incurred, local firms go bankrupt will cause the unemployment, the newfangled organizations which had not established enough yet can not hired these new unemployees, this cause the high unemployment rate. This is the main reason for indigent at Africa.Disease can move from country to country very fast because the people can travel to other countries by air, by bus, trains or other transportation in the short time. This cause the diseases spread very fast and became the reason of grand cases of dead at 2006 for bird flu from Indonesia and spread to other countries, 774 cases for SARS in 2003 at China and other East Asia countries, millions people dead because assistBrain drain talent will go out of the poor countries to the richers. This situation can be seen much at Africa, India and many poor countries all over the world. These countries finance to these students to go over sea study but they have never come concealment after graduated.Income distributionThirdly local e conomicThe economic can not stable when the nation pith to the worlds market, it will be easy affect by the world situation, let came back to the crisis at 1997, the economic of the world had been affected.The developed countries force the developing countries to reduce trade barrier but they keep for themselves by hamper the developing countries to merchandise agriculture products which are very important for they to receive foreign currency earning.If the nation opens the market too soon, sooner than establishing of the local organizations, the creating new jobs will less(prenominal) than the loss. The export of this nation will not develop, the import infringe instead, deficit become serious day after day. This nation will poorer and poorer.Finally the local societyThe develop countries will export the pollution to the developing and undeveloped countries by invest the pollution goods industries, second hand goods to these countries.Chapter 3 Advantages and disadvantages of ant i- globalizationAdvantagesAnti-globalization can warn to the world the significant problems of the world such as warming of the earth, pollution, forest destroy, greenhouse affect, and so on. So that the governments and organizations can perform the actions to reduce these affects. pollution as many countriesRacial discriminationSex discriminationThe war at Iraq and othersTo disclosure the truth that have never disclosure themselves of IMF, WB, WTOAnti-globalization also calls for champion the world when the actives raise the problems, the people all over the world can catch them then they may perform some activities to solve these problems.DisadvantagesThe demonstrations affected to social securities, many people die due to the extremist actions of the demonstration activities. The governments also have to perform many actions to control these extremist activities.The power of the voice of the anti-globalization still weak, the persuade ability of this organization also weak, can not appeal large group of people to do things, almost the activist just stand alone or just at a small group.The anti-globalization are always action without organization, they just a group of people who were hurt by the activities of one organization then stand up and perform anti actions.Lack of evidenceLack of effectiveChapter 4 The anti-globalization activities at VietnamIn general, the anti-globalization activities of Vietnam are not many. This is because Vietnam performs globalization too late. After 30 Apr 1975, Vietnam was achieved to be an independence country. Almost people agreed that during ten years after the independence reckon was the black period of Vietnam economic. Almost activities become stagnation famine incur in many areas event at Mekong delta which was the biggest farm in the country education, wellness care and other social welfare were totally ignored.The globalization of Vietnam begins at 1986 with the open market policy name socialist-oriented market eco nomy. Thank to this policy, the economic of Vietnam reversed, farmers got his birth land (event in temporary) for manufacturing and alive. Up to Dec 2001, US-Vietnam Bilateral Agreement was signed this is the very important step for recover the economic and became the first step to join into World Trade Organization (WTO).These are just some activities at Vietnam for this event to strike for higher rate of pay in the industrial zone Binh Duong province and Bien Hoa city at 2008 for some Taiwan firmsConclusionAccording to Yin Yang theory of Chinese, every thing has 2 faces positive and negative, the existing of anti-globalization also belongs to this theory, anti-globalization will exist parallel with globalization, this also the rules of the existing opposition to develop, and develop must contain opposition.Einstein also issued the theory for relative every thing

Environmental Geochemistry of Gold

Environmental Geo chemical science of gildedINTRODUCTION favourable is a chemical element with the symbol (Au) and atomic number 79. In its demonstrateed province, it is a bright, moderately reddish yellow, dense, soft malleable and ductile metal. Pure bullion has a denseness of 19,300kg/m3, though native gold typically has a meanness of 15,00kg/m3 (Marsden et al 2006). Because gold is inert at ambient temperature and pressure, there atomic number 18 very few naturally occurring compounds of the metal. The purity of gold (sometimes referred to as fitness) is expressed in karats. Pure gold is 24 karat (Boyle 1987). metal(prenominal) is one of the native earth metals that is of very high school value in our military personnel today.The current damage of gold per Ounce is approximately 1220usd (GFMS, Thomson Reuters, 2016). Gold plays a vital role in the economic development of a country. Gold, the noblest of metals, has been utilize by man for more than 5000 stratums (Ne lson et al, 2014). Its malleability, softness and resistance to tarnish, led to its earliest uses in art and currency. It is the metal choice for jewellery. Some of the countries where gold is mined are S erupth Africa, USA, Canada, China, Australia, Indonesia, Peru, Russia and so on The average concentration of gold in the earths crust is 0.005 g/t, which is much lower than most other metals, for example, copper (50% g/t) and silver (0.07 g/t)(Boyle, R. W.1979).Gold is commonly associated with other metals like iron, lead, zinc, copper and silver. Minerals most associated with gold are pyrite, marcasite and pyrrhotiteetc. Gold is the most noble of metals, and its geochemistry is conditioned principally by this fact baby concentrations of gold occurs in most natural substances. In sea piss, for example, there is approximately 0.012 move per billion (ppb) of gold, and in fresh water it is slightly higher at 0.02ppb (Boyle, R. W.1979). Its average concentration in the earths crust or lithosphere is approximately 5ppb, and in sedimentary rocks it may have concentrations of up to 2100ppb or 2.1 parts per trillion (ppm). At these concentrations 20 or 30 tons of rock must be processed to extract a single ounce of precious gold. As a result, gold can only be mined profitably where it is highly tightend by natural chemical and physical processes. Gold occurs in many several(predicate) rock types and geological surrounds and economic deposits are mainly of two types lode deposits (primary) and placer deposits (secondary)(BGS 2010). Gold is extracted by open cast or immunity excavation method, which depends on the geological settings of a deposit. Gold in its raw state is displayed in the diagrams below.PROPERTIES OF GOLD Physical PropertiesGold is both ductile and malleable. waxy meaning it can be drawn into wire forms. Malleable meaning capable of creation hammered into trend sheets. Gold is quite soft. It can be scratched by a penny. Its melting point is 1,064. 760C (1,948.570F) and its boiling point is about 2,7000C (4,9000F). Its density is 19.3 grams per cubic centimeter. Gold leaf is translucent and the transmitted light is light-green blue colour gold metal reflects yellow and red, leaving the greenish colour (Boyle R. W. 1979).Chemical PropertiesGold is known to be a noble metal. It is chemically inactive. This is because it is highly resistance to react with other elements. The oxidation state of gold ranges from -1 to +5. The +1 and +3 (Au (I) AND Au (III)) are the most common oxidation state of gold. It is resistant to the effect of most acids and therefore does not corrode easily. Apart from acids, gold does not combine directly with oxygen). Gold has one stable isotope, 197 Au. cobalt blue regia, a mixture of nitric and hydrochloric acids, has the ability to dissolve gold (Young and Derek, 2009).USES OF GOLDGold has been utilise to make jewellery and ornamental objects for thousands of years. Gold nuggets found in a str eam are easy to work and were probably one of the first metals used by humans. Today most gold that is newly recycled is used in the manufacture of jewellery. About 78% of gold consumed each year is used in the manufacture of jewellery. Special properties of gold make it good satisfactory for manufacturing of jewellery. These include very high lustre and its yellow colour. Pure gold is known as 24 karat gold. Pure gold is too soft, craftsmen conditioned that alloying gold with other metals such as copper, silver and platinum increase its durability.Gold is also used for medical checkup purposes, to treat small number of medical conditions. Radioactive gold is used in diagnosis. Gold as an extraordinary ductile and malleable metal, it is still cosmic demand in jewellery, medical applications, because of its uncomparable physical and chemical properties (Spitzer and Rodnei, 2004). According to (Renner et al. 2000), gold and its alloys are used for conductor material and low-voltage contacts for communication and information transfer equipment, where even very thin oxide layers would cause interruptions or failures in signal transfer. Below are the examples of processed gold.EXTRACTION OF GOLDGold panning, sluicing and mercury processes have been extensively used in placer archeological site to recover gold from primary sources. The primary sources of gold are alluvial gravel and auriferous quartz. Gold extraction may request comminution, mineral resources, pyro-metallurgical and hydrometallurgical process to be performed on the ore. Mechanical separation, pyro-metallurgical, hydrometallurgical and bio-hydrometallurgical technologies have been extensively used to recover gold from secondary sources (Fleming, 1992). exploit gold from year to year is always an increase, in which the more developed, ranging from mining system that uses simple system to a more modern touch on system. Gold mining was first carried out in alluvial areas. Processing system is als o very simple to do that is by panning using a tray, which then developed with gold mining wave table, and followed by gravity separation method using the amalgamation process with the capture of mercury.GOLD PROCESSINGAfter the extraction of gold from its ore, it is however passed through comminution (crushing / milling). This comminution process is divided into stages Refractory ore processing, crushing and milling.Once the size of the ore is scale downd, the process is then performed by separating the mineral concentration process gold from mineral impurities, consisting of several kinds of processing techniques process gravity concentration, amalgamation process, flotation process, leaching process.From the stage of the process, will then be obtained concentrate processing ores containing various metals. And the concentrate will be processed in order to obtain the value of gold in high purity chemical process. And a few stages of the sermon process through a process smelting, parting and aqua regia.After the treatment of the processed gold by the above processes, it is finally made into different forms, for example gold bars, jewelries, gold equipment etc. Below is a flow chart showing the processing of gold.GOLD DISCARDINGRecent research has proven Gold and other precious metals for example silver, palladium and platinum are discarded mostly through e- intemperance in our environments today. (Husman, 2004) revealed that in mobile phones, three quarter of the environmental impacts result from gold and palladium content. According to (Husman et al, 2007). Gold accounts for 16% of the total environmental weight of materials contained in macerate IT and telecommunication equipment (excluding monitors). UNEP (2005) reported that 20 to 50 million tonnes of small waste electrical and electronic equipment (sWEEE) are generated worldwide every year. Report shows that these discarded metals are being recycled and reused.GOLD WASTE AND contaminationAs gold is b eing extracted from mines, gold waste are concentrated in the rock piles, dogs and waste rocks. The waste from gold mines constitutes the largest single source of waste and pollution. As at 1997, South Africa produced an estimated 468 million tons of mineral waste per annum (DWAF, 2001). Gold mining waste was estimated to account for 221 million tons of 47% of mineral waste produced in South Africa, making it the largest, single source of waste and pollution (DWAF, 2001). There are more than 270 tailings in the Witwatersrand Basin, covering fire approximately covering 400 km in surface area (AngloGold Ashanti, 2004). These dams are mostly unlined and many are not vegetated, providing a source of extensive dust, as well as soil and water (surface and groundwater) pollution (Anglo Gold Ashanti, 2004).Historically impoundment on land was the preferred option for tailings presidential term. The environmental implication of this disposal option include contamination of streams and riv ers by acid mine drainage (AMD), contamination of streams due to surface run off from the impoundment area, air and water contamination due to wind erosion of dried-out tailings. The exposure of sulphide bearing rock materials to oxygen and water produces Acid mine drainage. Mine waste problems are numerous, but the most difficult problem to handle is the acid mine drainage (AMD) that emanates from both surface and underground workings, waste and development rock, tailing piles and ponds (Durkin and Hermann, 1994).TOXICITYGold mining has been reported to be a dangerous activity as the heavy metals, mainly Hg, Pb and As are released into the environment. There were studies based on the assessment of the above stated heavy metals and their presence in soil and water in Kenya, South Africa and other parts of Africa. These metals were selected because of their toxicity nature in similar mining environments.According to the United States Agency for Toxic substances and Disease Registry ( ATSDR, 1999) Hg, Pb and As are in the top list of hazardous substances. As and Pb are major metals in gold sulphide deposits, where they occur as minerals mainly in arsenopyrite (FeAsS) and galena (PbS), respectively. Under natural conditions, they are relatively stable. However, gold extraction from its ore breaks down these minerals due to exposure to oxygen and water, thereby making it acidic. quicksilver as a pollutant in mining is released during gold processing, when mercury is used to amalgamate gold so as to recover it from its ore. Cadmium is also another toxic metal, occupying scene seven in the list of hazardous substances, generally occurring as an isometric trace element in sphalerite. It is estimated that about 1.32kg of Hg is lost for every 1kg of (Au) produced (Harada et al., 1997). As, Pb and Hg are all known as poisonous metals which when taken in by humans causes lots of diseases.GOLD STANDARDSGold banal is referred to as monetary system in which the standard economic unit of account is based on a fixed quantity of gold. Three types of gold standard can be distinguished specie, exchange, and bullion. Most nations abandoned the gold standard as the basis of their monetary systems at some point in the twentieth century, although many hold substantial gold reserves. An estimated total of 174,100 tonnes of gold have been mined in human history, according to (GFMS Thomson Reuters, 2012). This is roughly equivalent to 5.6 billion troy weight ounces or, in terms of volume, about 9,261 cubic metres (327,000 cu ft), or cube 21 metres (69 ft) on a side. There are also other alter estimates of the total volume of gold mined.DISCUSSIONGold is defined as a chemical element with the symbol (Au) and atomic number 79. In its pure state, it is a bright, moderately reddish yellow, dense, soft malleable and ductile metal. Gold is one of the native earth metals that is of very high value in our world today. The current price of gold per Ounce is approxima tely 1220usd (GFMS, Thomson Reuters, 2016). It has different properties, which are physical and chemical properties. Physical properties which consist of the malleable and ductile nature of gold, density of gold and also its melting and boiling point. Chemical properties which is its resistance to corrosion and it is chemically inactive. Gold has been reported to be used for the production of jewelries, medals and monetary exchange.Gold can be recovered or extracted from primary source in placer mining by the use of panning, sluicing and mercury or cyanide amalgamation. In secondary sources the use of hydrometallurgy, pyrometallurgy and bio-hydrometallurgy has been applied to recover gold from ore. After the extraction of gold from its ore, its passed through crushing and and milling process. This is done so as to reduce the size before conducting other processes, which involves leaching, flotation, gravity concentration and amalgamation to separate the gold concentration from its i mpurities. And finally through a few stages of the treatment process which involves smelting, parting and aqua regia. The processed gold after the above treatment is then produced into various forms for example jewelries, medals etc. Discarded gold from e-waste and other sources is being recycled into new forms. Generally mine water waste, rock piles and tailings from mining has led to the pollution of our environment today. The most common problem concerned with mining is Acid mine drainage. (AMD), occurs when rock bearing sulphide materials are exposed to oxygen and water. The extraction of gold from its ore also causes the release of toxic substances for example lead, mercury, arsenous oxide etc. These substances, when introduced into our environment and spread through water bodies, it causes adverse effect to humans health. Gold standard is known to be a monetary system, in which the standard economic unit of account is based on a fixed quantity of gold. Three types have been d istinguished specie, bullion and exchange.CONCLUSION question has shown that gold is chemically inactive, which is because of its high resistance to react with other metals. It is proven that in its natural state, it occurs with other metals and minerals. The extraction of gold from its ore causes the exposure of this minerals and heavy metals in our environment. Heavy metals e.g. Lead (Pb), Arsenic (AS), Mercury (Hg). And sulphide minerals which are mostly common with ores, when exposed to oxygen and water produces Acid mine drainage (AMD). Mercury is introduced by humans in the extraction of gold to amalgamate with gold making it easier to recover from ore. These heavy metals are toxic substances, which when released into water bodies in our environment cause severe hazard to humans.REFERENCES50.6 EXTRACTION OF GOLDAngloGold Ashanti ( 2004).
