CYANIDE MANAGEMENT

The thickener overflow solution is neutralised with lime and recycled gypsum (seed) to a pH of around 10 or 11. The gypsum is recovered using a thickener with a bleed off to the CCD circuit. The gypsum thickener overflow solution is mixed with the scrubber solution and is the final cyanide return solution.

Cyanide Leaching Of Gold

Most cyanide leaching is carried out at a alkaline pH of between 10 and 11, depending upon lab testing of individual ores and the optimum leaching/chemical use rates. The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect ...
