Acid Leaching - Copper Ore Treatment Method
COPPER LEACHING. The application of hydrometallurgical leaching to oxide and combined oxide and sulfide ores depends mainly on obtaining solvent at low cost and in holding initial plant costs within feasible limits. Dilute sulfuric acid-ferric sulfate has been found to be an excellent solvent for oxide minerals as well as for such sulfide forms ...

Copper Production: How Is Copper Made? - ThoughtCo
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.

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a mixture of copper sulfides and iron sulfides.
