Oct 20, 2014 The equation is well known, but the successful application of this reaction in a gold mining operation is rarely straightforward. In a typical application, a slurry of the ground ore is mixed with cyanide in the presence of activated carbon. The carbon has a very high affinity for the aurocyanide complex and adsorbs the gold out of solution

Cyanide Use in Gold Mining Earthworks

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

Cyanide Gold Extraction Process JXSC Machine

Cyanide Gold Extraction Methods. The existing cyanide gold plant in China’s gold mines basically adopts two types of gold extraction process, one is a so-called conventional cyanidation process for gold extraction by continuous countercurrent washing with a thickener, and the gold is replaced by zinc powder (CCD method and CCF).

Gold cyanidation Wikipedia

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

Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold.
