    Copper extraction Wikipedia

    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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

    However, after the secondary recovery by acid leaching, some uranium remains in the copper concentrate as it proceeds to be smelted. Typically it would have 45% Cu and up to 0.15% uranium, and the uranium is recovered in the further copper processing. This creates a safeguards problem if the smelting and electrorefining is not done at the mine
