Acid mine drainage

Iron disulfide (FeS2) is the chemical formula for the mineral pyrite. This mineral has long been described and prevalent in modern and ancient history. Pyrite’s name originates from the Greek for fire, which is “pyr”. The Roman author Pliny the Elder described a stone which is thought to be pyrite. He described a stone used for grindstone, which would readily fire sparks or sulfur. He also commented on the heft, its resemblance to brass or copper, and its porosity. A Greek physician called pyrite

very important to the survival of everyone living on earth,but it has become unstable.One of the causes of this instability is mining.Mining causes millions of tons of waste to find their way up into the air and atmosphere,resulting in the creation of acid

management is recognized as one of the most serious environmental concerns in the mining industry. For mining activities, it will be no surprise that the metal recovery reagents and acid effluents are a threat to the ecosystem as well as hazards to human health. In addition, poor air quality and ventilation in underground mines can lead to occupational illness and death of workers. Electricity usage and fuel consumption are major factors that contribute to greenhouse gases. On the other hand, many sustainability

contaminated with acid mine drainage. Say a specialists amphibian lived symbiotically with a moss or algae in the lake ecosystem, and without intervention the species dramatically suffer. Superfund sites are a popular topic sustainability and conservation biologists should use their popularity in the nation to aide in the local community remediation methods. For example, I am working to sample vegetation, water quality, fish biomass, and macro invertebrates biomass in local acid mine drainage remediation

above the Mount Morgan mine site and below the Mount Morgan mine site were also compared. 8.1 Analysis of the Data It was hypothesised that the water sample from above the mine site would be of better water quality than the sample from below the mine site. It was found that this was, in fact, the case. As seen in Table 7.2, the above sample had lower acidity, hardness and conductivity than the below sample. Given that acidity is indicated by a pH of below 7, the below mine water sample was considered

There was an estimated 1 billion Unpeeled, Unopened and Unwanted food items are discarded annually in America. Food Rescue establishes programs to reduce waste in public school cafeterias. The EPA & USDA support, has resulted in a dramatic shift in food donation policies. Food rescue has grown exponentially in the past few years, but we still have a long way to go. American food production has a tremendous resource cost – 10% of the nation’s total energy budget, 50% of its land, and 80% of all

Another form of Nonpoint pollution is a type of pollution that 's where mining is taken place, Its called Abandoned Mine Drainage. The cause of it is usually because of coal mining and from people abandoning mines. It can impact the quality of the water has a few types like Acid mine drainage, alkaline mine drainage, and metal mine drainage The most common type is Acid mine drainage. It 's very acidic and has a lot of metals in its water. Being extremely toxic it has harmful effects on most organisms

Ely Copper mines representing 87% of currently operating copper Ely mines, and responsible for 89% of U.S. copper production in 2010. The Ely Copper mines were chosen based on an operating record of more than five years. These mines provide a representative view of the types of environmental impacts resulting from the development of copper porphyry deposits, focusing on pipeline spills, tailings failures and water collection and treatment failures. It was found that all of the mines (100%) experienced

near Durango, Colorado. Once the water was tested, there was an estimate more that 3 million gallons of wastewater in the River. Do you want to know what caused it? An abandon and dormant mine, had a pool of wastewater that had collapsed and went down to the river where we get our fresh water from. Most of the mines from the U.S. have produced 50 billion tons of untreated, unclaimed mining waste on public and private land. Also the ocean is polluted, and estimated 10 percent of the 260 million tons
