Acid mine drainage - Wikipedia

14/6/2004, · ,Acid mine, drainage, acid and metalliferous drainage, or, acid rock, drainage is the outflow of, acidic water, from metal, mines, or coal, mines. Acid rock, drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed may create, acid rock, …

7/10/2017, · Very ,high, pH can also cause chlorination to be ineffective. ,High, pH can be reduced with specialized ion exchange media, but the most common ,treatment, is to inject a mild ,acid, into the water line. It is normally a “point-of-entry” ,treatment,. With wells, the normal place to inject the ,acid, is just before the pressure tank.
