mining sulphide ore of zinc

  • Zinc

    The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning ).

  • Concerns Over Sulfide Mining Resurface With Tiffany's Bill

    Sulfide mining is one of the ways we get metals such as copper, gold, silver and zinc. Tons of rock loaded with the metallic minerals are crushed and processed to extract the valuable metals. But that rock is also loaded with other minerals called sulfides, and when exposed to air and water they can leach acid into nearby streams and groundwater.
