Effect of Oxygen on Gold Leaching

In simplified terms, the Effect of Oxygen on Gold Leaching can be summarized in saying: The dissolution rate of gold in alkaline cyanide solutions under atmospheric conditions, and at practical cyanide levels, is directly proportional to the dissolved oxygen concentration. The rate of dissolution of gold in alkaline cyanide solution is dependent on a number of factors, principally the solution ...

Improving the process performance of gold cyanide

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.%.

Tank leaching - Wikipedia

Tank vs. vat leaching Factors. Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;
