Apr 11 2017 Copper Ore Processing Methods 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 ore mined is concentrated.
