3. Carbon In Leach (CIL) The carbon in leach process integrates leaching and carbon in pulp into a single unit process operation. Leach tanks are fitted with carbon retention screens and the CIP tanks are eliminated. Carbon is added in leach so that the gold is adsorbed onto carbon almost as soon as it is dissolved by the cyanide solution.

Use in Mining International Cyanide Management Code

The milled ore (slurry) is conveyed to a series of leach tanks. The slurry is agitated in the leach tanks, either mechanically or by means of air injection, to increase the contact of cyanide and oxygen with the gold and silver and enhance the efficiency of the leach process. The cyanide then dissolves gold and silver from the ore and forms a

Improving the process performance of gold cyanide leaching

Due to the inherently low concentration of gold in ore and the relatively long retention time required for gold to dissolve, gold cyanide leaching reactors are usually very large, with a size of up to 5000 m3. For the same reasons, the solids content in tank leaching is kept at a high level, around 40 wt.%.

Cyanide Leaching Of Gold mine engineer

Leaching gold from sulfide ores is difficult, at best. Generally, the recovery for cyanide leaching of sulfide or refractory ores is no better than 30%, which is not a worthwhile venture. The use of alkalies such as calcium oxide, will prevent the decomposition of cyanide in solution to form hydrogen cyanide gas.
