Contaminated mine water is generated when rock containing sulphidic minerals is exposed to water and oxygen, resulting in the production of acidity and high concentrations of metals and sulphate in the water.

Mine drainage, process water and storm water associated with industrial activities are the main types of water produced in mining operation. The two primary aims of the treatment of contaminated mine water are to neutralize acidity and removal metals.
