Extracting gold without cyanide Chemical Engineering

Cyanide is used in more than 90% of global gold production, but producers are facing increasingly tough regulations restricting the use of cyanide due to environmental and health concerns. The CSIRO technology replaces cyanide with thiosulfate, a nontoxic, mobile-plant alternative. It is a simple vat-and-heap-leach process involving low capital
