Getting a Handle on Refractory Ore May Determine Gold’s

2021.10.21  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. A refractory ore generally contains sulphide minerals, organic carbon, or both, generally leading to a
