AMD is a promising domestic ,source, of rare earth elements because it contains high levels of minerals. AMD occurs when pyrite rock is unearthed by mining activity, which oxidizes when it touches water and air, and creates sulfuric ,acid,. Sulfuric ,acid, breaks down surrounding rocks and causes toxic metals to dissolve into water.

Acid mine, drainage water, characterised as having a low pH, and high metal and sulphate concentrations, has a detrimental effect on ecosystems in overflow events. Commercial alkali such as lime, caustic and limestone are used to raise the pH of AMD waters, which in turn facilitates the precipitation of metals and formation of gypsum (CaSO 4.2H 2 O).
