What is Acid Mine Drainage? Acid mine/rock drainage occurs naturally within some environments as part of the rock weathering process, but is significantly exacerbated by mining, usually within rocks containing an abundance of sulfide materials. As water comes in contact with the sulfur, it creates a sulfuric acid.
