Cyanide Process

Cyanide Process

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. The slurry formed is treated with activated zinc or carbon for the extraction of ...
