Cyanide Process Gold Cyanidation Process Gold
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 to favour the reactants and bring them to equilibrium.
