The gold contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The gold is within the sulfide mineral matrix, which is not exposed (and therefore can not be dissolved by) a cyanide leach solution. Also the ore contains carbonaceous matter which absorbs gold in the conventional leaching process.

The environmental hazards and toxicity of cyanide have increased the interest in a new cyanide-free gold process (Aylmore, 2005).The typical challenges related to the new development-stage cyanide-free gold processes are related to the high costs of chemicals, selectivity for gold leaching, and final gold recovery from the solutions (Hilson and Monhemius, …

Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).

The gold cyanidation process, also known as gold CIL (Carbon in Leach) or CIP (Carbon in Pulp), is a hydrometallurgical technique used to extract gold from ore by converting the gold into a water-soluble coordination complex. ...
