Merrill-Crowe process is used for gold or silver precipitation from 11 dilute sodium cyanide solutions and is favored for gold cyanide containing high silver concentration. MINTEK researchers suggested that zinc cementation should be considered as a process alternative to electrowinning for direct treatment of carbon eluate in the CIP process ...

In the cyanide production process, especially for ores containing more sulfide components, it is usually necessary to control the concentration of lime in the leaching operation. For the gold concentrate cyanide plant, the CaO concentration of the general control leaching process is between 2 and 5/10,000.

The gold cyanidation process has certain requirements on the performance of the leaching (adsorption) agitation tank. Under the condition of small power consumption, the particles with monomer separation or exposed surface gold in the pulp cannot be deposited in the tank, and the pulp, cyanide, lime and air should be fully mixed in the tank to reach the suspension state.

Cyanidation tanks were assessed and found to be leaking fluids thus also leaking gold. A program have been envisioned on how to improve these gold cyanidation tanks so that full gold recovery may take place.
