  • Difference Between Hydrometallurgy and

    2020-7-5  The key difference between hydrometallurgy and pyrometallurgy is that in hydrometallurgy, we use an aqueous solution to extract metals from the ore, whereas in pyrometallurgy, we use high temperatures to extract metals from the ore.. Hydrometallurgy and pyrometallurgy are two main branches in industrial chemistry. Both these processes are important in extracting metals from their naturally ...

  • 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.
