John Muir, a renowned naturalist, mentioned “Hidden in the glorious wildness like un-mined gold”. However, nowadays this wise saying can be converted to “Hidden in the glorious wildness like un-recycled gold”. Gold producing requires huge amounts of money and causes environmental pollution since the efficiency to extract pure gold from mined one is extremely low and unjust exploitation of labor occurs during the mining process. To prevent these problems, the business of recycling gold was founded and it is rising recently. By examining the benefits of recycling gold in terms of environment, economy and humanity, the importance of reprocessing gold can be emphasized.
In the first place, re-processing gold helps protect the environment.Since the process starts with accumulating gold from articles for daily use, it does not need to mine to collect gold. Therefore, harmful materials such as mercury and cyanide which occur during the mining process do not come about. According to NYT, in gold mine, almost 500,000 tons of soil and rock is cut. They are chemically treated and pollute the l...
...sumption, creates emission of greenhouse gases and other harmful chemical materials. Once released into the air, it can cause environmental problems, which in turn threatens not only the environment, but also the health of the people who live in it. In order to reduce the use of energy to help protect our planet and our health, the diamond mining industry has implemented renewable energy programs to monitor energy and carbon emission. Since its beginning, mining company PHP Billiton program has saved an equivalent of one million liters of diesel fuel per year at their Ekati Diamond Mine in Canada’s Northwest Territories. The health of the environment and the health of humanity are as one. Whatever we do to our planet, we do to ourselves. Reducing energy consumption of diamond mining not only helps protect our planet, but also helps protect the health of our people.
The fortune of silver and gold discovered in Colorado’s mountains were locked inside complex ores consisting of granite, quartz and other metals that rendered them useless, unless they could be separated (Egan. NPS). Miners originally imported stamp mills and Spanish arrastras to extract the gold and silver but both these methods were inefficient and lost upwards of 70 percent of the sought after mineral (NPS). In 1867, chemistry professor Nathanial P. Hill discovered an efficient method called the Swansea process to separate the precious metals and opened the Boston Colorado Smelter in Blackhawk (NPS).
Dental amalgam is a commonly used restorative material that contains mercury and is of particular concern due to the potential detrimental effects it has on both the environment and humans (Chin et al, 2000). Some of the generated amalgam-contaminated sludge is released into the sewage system. Extracted or missing teeth that contain amalgam fillings as well as amalgam-contaminated waste, like trituration capsules and cotton rolls are expelled along with solid waste and often incinerated as well (Chin et al, 2000). The negative ramifications associated with dental mercury usage is on large a result of poor management of dental amalgam waste (Chin et al, 2000). To address these concerns, health professionals have attempted to implement programs that promote positive environmental action. For example, the DCW (Dentists for Cleaner Water) program involves the installation of dental amalgam separators with further measures put in place to decrease dental amalgam waste entering the water system by 95% (Adavb.net, 2016). To reduce waste, dentists are encouraged to slightly modify their usual habits such as purchasing in bulk, limiting single use items and setting printers for double-sided and greyscale printing. It is important for health professionals to be aware of the potential ecological and public health risks associated with
Gold is one of the most valuable materials all around the world. This jewel has its own glittering appearance and shiny color which induce people to desire to possess it. That’s probably why Europeans in the middle age have explored new continents and invaded other civilizations to find this glittering material. Americans also had given much endeavor to mine that valuable jewel in the time of gold rush. Investigating these events, gold has immensely affected the world history; the Age of Exploration, invasions of Spaniards, and the development of California.
Gold bears quite a number of chemical properties that I will discuss in details down here. These point out on how gold behaves at various conditions. The chemical formula of gold is Au which is derived from its chemical name. When it comes to gold’s activity, it is not chemically active. This means that it greatly resists any kind of chemical reaction. In most cases, it rarely reacts with other chemicals. Gold is easily reduced from a compound to become a metal. It has two main compounds. These compounds are the Chloral-auric acid as well as the auric chloride. When we come to how gold reacts with certain acids, it is clear that there is an acid that is very able to dissolve this element. This acid is known as Aqua regia and is a combination of hydrochloric and nitric acids. Gold is not able to react with non-metals. Under this case, it only reacts with halogens and forms what is known as halides. The main alloys that can be used to make gold harder include platinum metal and silver (Tocci,
Gold is recyclable material and it has a definite supply chain systems. In contrast, some sort of gold has particular features, including its natural value and handiness. And these have created it a possible source of investment for unlawful armed groups complex in civil wars and revolts. It is essential that the society take responsibility to reduce misapplication of gold. The uses of gold are enormous. Gold is not a decorative material anymore. Its usages are being more fundamental and essential to our contemporary generation. Consequently without using gold and culture of gold, people would be living in totally different way. Possibly, A lifetime is less technologically developed and unquestionably the world and cultures are less beautiful.
Objectives • To evaluate the difficulty of mining and reclamation To calculate costs, expenses, income, and profit from a hands-on mining exercise. • To evaluate the effectiveness of reclamation and its added costs to mining. To describe the increasing rarity of some non-renewable mineral resources. Introduction Minerals play an important role in our day-to-day life, but we often do not contemplate how the minerals are obtained. Minerals are scattered all over the world, just like any other resource.
The usage of gold is not limited to banks and jewelry industry. This metal is also usable to a wide array of industries, such a medicine, electronics, dentistry, and aerospace.
Though it has had many negative impacts on the environment in the past, mining is a vital industry completely necessary to our economy and lives. Nearly every item we use or encounter in our day to day lives is mined or contains mined products. Without the excavation of such materials things like computers, televisions, large building structures, electricity, and cars would not be possible. Virtually every technological and medical advance uses minded materials, without which millions would suffer. Some examples of minerals in the home include the telephone which is made from as many as 42 different minerals, including aluminum, beryllium, coal, copper, gold, iron, silver, and talc. A television requires over 35 different minerals, and more than 30 minerals are needed to make a single personal computer. Without boron, copper, gold and quartz, your digital alarm clock would not work. Every American uses an average 47,000 pounds of newly mined materials each year, which is higher than all other countries with the exception of Japan, which is a staggering figure representative of our dependence and need for mined minerals. Coal makes up more than half of nation’s electricity, and will continue to be the largest electrical supplier into 2020 & accounting for some 95 percent of the nation's fossil energy reserves – nine of every ten short-tons of coal mined in the United States is used for electricity generation. As the population of the world grows more mineral resources must be exploited through mining in order to support the rising demand for such products. Though it may present a hazard to the environment and those physically located nears the mines, the materials extracted from mines...
When most people hear the word recycling they think of plastic water bottles, milk jugs, or even old paper that they can reuse, but this is not necessarily the case anymore. Scientists and researchers have discovered a new form of recycling that is going to help better the environment and it can even help make people money! Smokers around the world do not think about recycling their used cigarette butts, but this new form of recycling has changed some of their minds on this subject. Recycling has been a major environmental issue, but most people have forgotten about it or they just do not care for it anymore. Paper recycling dates back to as far as 400 B.C. Some people even say that the early Romans recycled their bronze coins so that they

Mining is the process or industry of obtaining minerals from the earth. Topics in this paper I’ll be specifically discussing are pros and cons of mining, structures of a mine, mining in general, California gold rush, diamonds in Africa, and comparison of diamond and gold mines.
Have you ever wonder what can you do about the bottles and cans you find around you? People that doesn?t care about the world being clean is littering the place. It makes things very difficult to put up for. Recycling cans and bottles can help save the earth form waste and trash buildup and can make new things. I think that recycling should be mandatory and there should be recycling cans in various locations at school and everywhere else.
In our days, mining for resources is inevitable. The resources we need are valuable in everyday life. Such resources mined up are coal, copper, gold, silver, and sand. However, mining poses environmental risks that can degrade the quality of soil and water, which can end up effecting us humans if not taken care of and many of the damages are irreversible once they have occurred.
