Maximize Precious Metals Recovery with CCD Circuits and High-Density Thickeners. Leaching (lixiviation) is commonly used for recovering a wide variety of metals from ores, including precious metals. A lixiviant dissolves the desired metals from the ore; cyanide leaching, for example, is widely used to extract gold.

The cyanide dissolves the gold content and the gold is adsorbed on the carbon: the carbon is subsequently separated from the slurry for further gold removal. Carbon-in-pulp CIP, a precious metals leaching technique in which granular activated carbon particles much larger than the ground ore particles are added to the cyanidation pulp after the ...
