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.Process of Cyanide Gold Extraction,Pachuca aeration gave better gold extraction and lower cyanide consumption than bottle agitation. With the former more copper was found in solution, and less thiocyanate was formed; with bottle agitation the reverse was the case, in addition to which copper cyanogen complexes were found in the filter cake.Cornstarch Replaces Cyanide In Gold Extraction | Popular,,Cornstarch Replaces Cyanide In Clean New Gold Extraction Method Scientists accidentally discover a new way to isolate gold that is much safer than existing processes, which use toxic cyanide.
