Geology and mining — MineFacts
Sulphide mineral is stable as long as conditions are oxygen deficient, but becomes unstable in contact with oxygen or other oxidising substances. For this reason, mining waste containing sulphide mineral is often covered in dense layers of soil or water to prevent oxygen reaching the waste. Pyrite (FeS₂) is the most common sulphide mineral.
