Lead is almost always contained in sulfide ores as galena, or lead sulfide 45. Waste rock material from mines that contain metal sulfides can lead to sulfuric acid drainage when left out in the open air. Tailings also contain minerals and materials that can lead to dangerous runoff and water contamination when stored improperly.
