    Techniques of copper recovery from Mexican copper oxide ore

    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. The results indicate that an ore containing 19.01 copper could be obtained at a recovery ratio of 35.02 by using sodium sulfide and butyl xanthate flotation.
