  • Cyanide ProcessGold Cyanidation Process Gold Leaching

    In the process of leaching a dilute form of sodium cyanide is added into the ore containing the gold. Since gold is soluble after the leaching process it is free to move through the membrane while the rest of ore cannot pass through the membrane. Lime is added to sodium cyanide to make the pH in between 10-11 so as to favour the reactants and

    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).
