  • Copper In History

    Oct 18 2014  Most hydrometallurgy approaches end with a process called electrowinning in which electrified anodes are introduced into the leach solution in order to extract the metal Today copper mines produce up to 9 million tons of copper every year with most of the biggest mines found Peru and Chile One of the largest mines in the U.S the
