ECONOMICS OF REFRACTORY GOLD ORE PROCESSES

Refractory gold ores present a number of problems to the gold producer. Much has been written about the suitability of particular pretreatment processes for specific gold ores. We at Hazen Research have had the opportunity to participate in the development and application of a number of gold ore processes and to review others'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 pre-treatment in order for cyanidation to be effective in recovery of the gold.refractory gold ore crushing process,refractory gold ore crushing process Description : developments in the processing of refractory complex gold ores have resulted in the introduction of a variety of. » Learn More. primary crushing plant in refractories. clay crusher machine for refractories - Rocks Process -KWS.
