Environmentally friendly gold recovery CSIRO

Dec 6, 2016 . The novel gold recovery process replaces cyanide with thiosulphate a nontoxic chemical helping to reduce the risks and environmental impact of gold processing operations. Thiosulphate is effective at picking up gold in leach tanks to create a goldthiosulphate complex. The gold can be separated.

Gold cyanidation Wikipedia

Gold cyanidation 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.
