Recovery Refractory Resources - SGS
refractory gold ore is gold-containing ore that is resistant to recovery by direct cyanidation and carbon adsorption processes. More specifically, it is an ore that has a gold recovery rate of less than 80% when direct cyanidation is applied to it. Dr Chris Fleming, senior metallurgical consultant at SGS Minerals, says: “In the
