Effect Of Iron Mining On Water Quality

Mining and Water Quality

Mine drainage is metal-rich water formed from a stone reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.

IMPACTS OF IRON ORE MINING ON WATER QUALITY - A COMPARATIVE STUDY OF INDIA AND LIBERIA. As most of the mines use overburden as backfilling material for mining areas, ground water contamination may also result from leaching activities, which may have severe health impacts. Iron ore tailing usually contain trace of Hg, Se, Cu, Pb, Zn, As, Mn, etc.

Effect Of Iron Mining On Water Quality

Acid mine drainage (AMD) is metal-rich, acidic water that is the result of water from mining activities flowing over or through rocks containing pyrite, a sulfur bearing mineral. This water reacts with pyrite and air to form sulfuric acid and dissolved iron.
