    A Conceptual Process For Copper Extraction From

    Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity.(PLS) from the leach residue. PLS is sent to the copper solvent extraction circuit for selective copper recovery using a commercial organic extractant. The extractant is loaded with copper and then washed to remove entrained chloride and impurities. After washing the organic, the copper.
