  • Copper Ore Hydrometallurgy and Pressure Leaching

    Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult-to-concentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electro-winning (EW). It can produce either copper cathode or copper sulphate crystal.

    Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
