In accordance with this invention there is provided a process for the recovery of gold from leach pulp comprising the steps of: (i) diluting the leach pulp to provide a specific gravity thereof which is less than that of activated carbon to be used for effecting gold extraction; (ii) contacting the diluted pulp with activated carbon inاحصل على السعر
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.احصل على السعر
