Operations and waste products associated with metal extraction and processing are the principal causes of environmental concerns about metal mining. Concerns include: Physical Disturbances. The largest physical disturbances at a mine site are the actual mine workings, such as open pits and the associated waste rock disposal areas.

Environmental Impacts. Acid mine drainage (AMD) refers to the outflow of acidic water from coal mines or metal mines, often abandoned mines where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this …
