Jan 23 2017 · Types of Water Pollution from Mining There are four main types of mining impacts on water quality 1 Acid Mine Drainage Acid Rock Drainage ARD is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water Acid Mine Drainage AMD is essentially the same process greatly magnifiedGet Price
The environmental challenges from coal mining include coal mine accidents land subsidence damage to the water environment mining waste disposal and air pollution These are either environmental pollution or landscape change A conceptual framework for solving mine environmental issues isGet Price
Water flowing through active or abandoned mine sites can become polluted by the material being mined1 By far the most common mine drainage problem is that of acid mine drainage AMD Sulfuric acid is produced when water interacts with sulfurbearing materials in the presence of oxygen and common bacteria1 The acidic water formed by this process can dissolve many metals inGet Price
4 Coal fires In many countries there are problems like coal fires generally seen in mining areas which have caused a lot of environmental pollution The coal fires that occur underground can be a blend of several gases like nitrous oxide carbon dioxide methane sulphurGet Price

Mar 02 2019 · pH is a measure of how acidicbasic water is The range goes from 0 to 14 with 7 being neutral pHs of less than 7 indicate acidity whereas a pH of greater than 7 indicates a base pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the waterGet Price
Jan 23 2020 · As this acidic liquid flows into larger bodies of water it is diluted Howvever over time acids can accrue and lower the overall pH of the body of water Acid deposition also causes clay soils to release aluminum and magnesium further lowering the pH in some areas If the pH of a lake drops below 48 its plants and animals risk deathGet Price
