Copper Ore Processing Methods

2017-4-11  The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper

Copper Production: How Is Copper Made? - ThoughtCo

2019-9-26  Sulfide Copper Ores . Virtually all sulfide-type copper ores, including chalcocite (Cu 2 S), chalcopyrite (CuFeS 2) and covellite (CuS), are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.

12.3 Primary Copper Smelting

2015-9-10  Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
