2. Preventive and corrective techniques of acid mine drainage. Preventive techniques are those whose objective is to prevent the production of acid effluents from the mine. On the other hand, corrective techniques are designed to treat the acidic waters produced by mining, so that they stop being a threat to the environment .
The most serious problems with acid mine drainage are confined to Western Maryland, Northern West ia, Pennsylvania, Western Kentucky, and along the IllinoisIndiana border (USEPA, 1995). The following is a table of the concentrations of constituents in the coal mine drainage for the, Illinois, Kentucky, Maryland, and West ia.

Acid mine drainage is a major issue facing any life which relies on a clean water supply, from plants, to fungi and bacteria and, humans. Although technology has now been trialled to deal with the effects of AMD, large businesses and governments in most of the world are not stepping up to their responsibilities.
in the process. Sulfuric acid and H+ ions that have been formed can leak into the ground and surface water turning it acidic, causing environmental damage. Heavy ions such as iron, zinc, and arsenic leak during acid mine drainage. When the pH of this solution rises, as a result of dilution by fresh water, these ions precipitate, forming
"In addition, acid mine drainage associated with mining activities is the greatest current concern relating to groundwater resources," said the MEC. However, the findings of the report note that AMD can also be seen as an opportunity in the form of a valuable water resource if mitigate.
Acid Mine Drainage. AMD Water that is acidic, usually containing metals such as iron. However AMD can also mean Alkaline Mine Drainage. Water has a net alkaline solution.
Acid Mine Drainage (AMD) / Acid Rock Drainage (ARD) Acid Rock Drainage as a concern and part of all metals and mining operations. ARD is often mislabelled AMD or Acid Mine Drainage too. So, to better understand AMD and ARD, let's begin by defining some terms like pH The standard measure of acidity.
In a nutshell, acid mine drainage is a form of water pollution that happens when rain, runoff, or streams come in contact with rock that is rich in sulfur. As a result, the water becomes very acidic and damages downstream aquatic ecosystems. In some regions, it is the most common form of stream and river rock, especially one type of mineral called pyrite, is routinely ...
Mar 01, 2006· Impacts of acid mine drainage. High concentrations of metal ions and acidity render the water unsuitable for drinking, irrigation and industrial applications (it would damage pipes and machinery). Prior to any mining operations, the water may have been used .
Naturallyoccurring bacteria can ac celerate AMD production by assisting in the breakdown The mining of certain minerals, including gold, of sulﬁde minerals. copper, and nickel, is associated with acid drainage Also referred to as acid rock drainage (ARD), AMD problems that can cause longterm impairment to emanating from mine waste rock, tailings, and mine waterways and biodiversity.
Water Solutions: Discussion Questions for Acid Mine Drainage Video: Acid Mine Drainage and Precipitates General Level (Grades 612) 1. How does coal mining cause acid mine drainage (AMD)? 2. Discuss the common characteristics of solutions with a pH of less than 7. 3. Discuss the common characteristics of solutions with a pH greater than 7. 4.
Acid mine drainage (also sometimes referred to as acid rock drainage) is a wellunderstood process2 and arises primarily when the mineral pyrite ('fool's gold') comes into contact with oxygenated water. The pyrite undergoes oxidation in a twostage process, the first producing sulfuric acid and ferrous sulfate and the second orangered ...
Jan 20, 2012· What is acid mine drainage? Well, mining means that rock is being removed to uncover valuable minerals like gold, copper, iron or coal. It is safe to say that most of this rock has not been exposed to oxygen for a long time, if ever, and therefore have been in a state of anaerobic conditions. The process of exposing minerals like pyrite to oxygen is called oxidation.
