SulfideOre Copper Mining Boundary Waters ... SCOUTER Forum

Jan 17, 2018· In every direction, interconnected waterways laced the forest, and when considering sulfideore mining, the issue of water is central. When exposed to air and water, sulfide ore in which copper and other minerals occur creates sulfuric acid and generates heavy metals and other pollutants. This is sometimes called "acid mine drainage."
