sulfide mining benefits

What is Sulfide Mining? Mining Action Group

If sulfide ore or sulfide tailings are exposed to water and air during mining, a chemical reaction creates sulfuric acid – basically battery acid. There has never been a sulfide mine that has not polluted nearby water resources. Pollution from sulfide mining is very expensive to fix, and a burden for taxpayers. The legacy of sulfide mining is Acid Mine Drainage.
