Cyanide Leaching Of Gold - Mine Engineer.Com

Much thought and design goes into the making of a heap leach, to derive the best, most economical solution for recovering the gold from the ore. Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution.

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;

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.%.
