The sulfide concentrates are typically smelted in such furnaces as the Outokumpo or Inco flash furnace or the ISASMELT furnace to produce matte which must be converted and refined to produce anode copper Finally the final refining process is electrolysis For economic and environmental reasons many of the byproducts of extraction are reclaimedIn this process copper and precious metals remain as a pyrophoric residue that re quires separate treatment Use of electrical cells equipped with inert cathodes is the most com mon technology for nickel refining Electro winning in which nickel is removed from solution in cells equipped with inert anodes is the more common refining process
