AMD is the result of oxidization of iron pyrite (fool's gold), closely associated with the ore bodies that host gold, uranium and coal in South Africa. Stated simplistically, the pyrite is highly reactive to oxygen, which causes the generation of acid, often assisted by the presence of a bacterium called Thiobacillus feroxidans.Web
