Zinc ores typically contain three to eleven percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation. Once concentrated, the zinc ore is transferred to smelters for the production of zinc or ...
