Cyanide Process - Gold Cyanidation Process | …

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 bring them to equilibrium.

Vat Leaching of Finely Crushed Gold Ore

Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak ...

Leaching in Metallurgy and Metal Recovery

One example of a leaching process that uses vat leaching is gold cyanidation, the process of extracting gold from low-grade ores. In this process, a dilute solution of sodium cyanide (NaCN) is used to leach the Au into solution. The concentration is usually 0.01-0.05 % cyanide, or 100-500ppm. It should also be noted that the alkalinity of this ...
