The Metallurgy Of Cyanide Gold Leaching – An Introduction ...

Oct 20, 2014 Depending on all the other variables and costs associated, some projects can be viable with a gold grade as low as 0.5 g Au per tonne of ore, with sufficient tonnages. With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached.

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.
