Cyanide recovery by tailings washing and pond stripping

Cerro Vanguardia in Argentina operates a two stage counter current tailings wash, with high pressure HCN stripping/scrubbing (Botz et al., 2004). Typically, the final washed solids from a conventional tailings thickener will still require treatment by a detoxification or other process to remove the significant residual soluble cyanide species.

Counter Current Decantation Design Formula

The principle of Counter Current Decantation is simply that, when water or solution is to act upon solids, both are made to pass, in contact, in opposite directions, so that at each end the strongest or most potent portion of either is acting upon the weakest or most exhausted portion of the other. The recovery of dissolved gold and silver from slime pulp in the cyanide process, as first

The process design of gold leaching and carbon in pulp

Although air agitated leach tanks were commonly used in the industry, mechanically agitated reactors are preferred due to lower operating costs. Typical residence times in the leach section may range from 2040 hours depending on the head grade and nature of the ore and the number of leach reactors in series may range from 6 to 12.
