Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) 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 ...
Mining companies pay treatment charges (TCs) to smelters to have their concentrates turned into refined metal. The charges fall when supplies dwindle as smelters compete to find supply.
