Gold cyanidation

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex.It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Percolation Heap leaching, (see Mular et al. pp. 15711630, loc. cit.) is very widely applied to the ores of copper and precious metals, but percolation is also conducted on a smaller scale in batch tanks or vats and in continuous or dump extractors. In the heap leaching of low grade oxidized gold ores, for instance, a dilute alkaline solution of sodium cyanide is distributed over a heap of
