Gold extraction Wikipedia

A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pretreatment in order for cyanidation to be effective in recovery of the gold.
