    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 A refractory oreOver the years, refractory ores and pyrite concentrates from different gold deposits constituted the feed to the facilities Historical plant performance indicated that the roasting temperature was the main variable affecting the structural characteristics of the calcine, which in turn affected the recovery of gold by cyanidation Gold recoveryGold recovery from higharseniccontaining ores atAlluvial gold processing plant / 90%+ Gold Recovery Ratio Hengcheng offers complete project solutions for Alluvial Gold Processing Plant We are one of the leading project suppliers for Alluvial Gold Wash Plant Equipment and we work closely with our customers to fulfill their specific needs for customized package solutionAlluvial gold processing plant gold wash plant supplier
