how to process copper oxide

(PDF) A STUDY OF LEACHING OF COPPER OXIDE ORE BY .Mexican copper ore is a mixed ore containing mainly copper oxide and some copper sulfide that responds well to flotation. The joint techniques of flotation and leaching were studied.Copper mining. Chemical reactions.The blister copper produced by this process is 99% pure copper. The name 'blister' copper comes from the fact that this final process produces bubbles of sulphur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining.
