Acid mine drainage sources and hydrogeochemistry at the Yatani mine
Mine drainage samples are Ca 2+ –SO 4 2− type waters, except for sample M-1 (from near the adit mouth), which is a Ca 2+ –HCO 3 – type water. Mine drainage samples M-1 to M-14 from old mine workings has lower pH and higher EC values than river water, indicating significant impact of AMD on groundwater quality.

Surface mining inevitably produces major environmental disturbances since vegetation, top soil and underlying soil mantle have to be removed to gain access to the minerals beneath. In underground mining, large quantities of waste are produced, which commonly exceed the volume of minerals (Plumlee et al., 1993; Salomons, 1995; Younger, 1997).
