Abstract
The solubility of metallic of zinc occurring in the cementation of gold and silver has been established in a laboratory-size Merrill-Crowe apparatus. The effect of several parameters, namely, cyanide, oxygen, gold, silver, and lead nitrate concentrations on the solubility of zinc were determined. In this system, an increase in concentration of cyanide, oxygen and gold or silver increases zinc solubility but does not always promote the efficiency of gold and silver precipitation. Zinc is consumed largely by oxygen and water. A single mechanism of the enhancement of precious metal cementation in the presence of lead nitrate does not appear to be operative. The enhancement is probably due to several phenomena.
