Mining | Water for all

Mining results in four main types of pollution: acid mine drainage (AMD), heavy metal pollution, processing chemical pollution, and sedimentation. Chemical waste can severely damage the surrounding ecosystems, as well as poison humans who drink for the water.

pH, is the measure of the acidity or alkalinity of an aqueous solution. Solutions with a ,pH, less than 7 are ,acidic, and solutions with a ,pH, greater than 7 are ,alkaline,. Pure water has a ,pH, very close to 7. Solutions of acids and alkalis can vary widely in their acidity and alkalinity.

6/1/2019, · The effluent from, Wastewater, Treatment Plants (WWTPs) can increase, alkalinity, to a stream. The wastewater from our houses also contains bicarbonate and carbonate from the cleaning agents and food residue that we put down our drains., Alkalinity, Degree and Levels., Alkalinity, with a pH of higher than 8.3 is mostly in the form of carbonate (CO 3 2-).

Acid mine drainage - Wikipedia

In cases where drainage from a mine is not acidic and has dissolved metals or metalloids, or was originally acidic, but has been neutralized along its flow path, then it is described as "neutral mine drainage", "mining-influenced water" or otherwise. None of these other names have gained general acceptance. Occurrence

21/2/2020, · However, ,mining, waste can also contain large quantities of dangerous substances, such as heavy metals. Extracting and processing metals and metal compounds can result in acid or ,alkaline, drainage. In addition, tailings management is risky, and often involves residual processing chemicals and elevated levels of metals.

A pH less than 7 is ,acidic, and a pH greater than 7 is ,alkaline,. The pH scale is logarithmic so for every one unit of change in pH there is a tenfold change in ion concentration. This means a solution with a pH of 3 is 10 times more ,acidic, than a solution with a pH of 4 and 100 times more ,acidic, than one with a pH of 5.

The authors propose the use of acidic mine drainage to neutralize alkaline flotation leachate. The conducted experiments indicated that it is possible to reduce the pH from ~12 to values close to neutral by using a volume of acidic mine wastewater four times smaller than that of flotation wastewater.

The pH is expressed numerically ranging above 0 thru 14. A pH or 7.0 is neutral and pH below 7.0 is, acidic, and pH above 7.0 is basic or alkaline. Modifying the ionic charge of wastewater changes the solubility of certain solids and also allows for physical solids to attract to each other.
