| Abstract: | A combined process of beneficiation and hydrometallurgy for the arsenic-containing gold ores at ambient temperature and pressure was presented, including floatation fine grinding, intensified alkaline leaching pretreatment and cyanidation. Experimental results on a particulate disseminated arsenic-containing gold ore showed that the concentrates contain Au of 63.8 g/t with the yield rate of 5.51%. The floatation recovery of gold is 92.08%. After fine grinding and intensified alkaline leaching pretreatment, the gold leach rate by cyanide in concentrates is enhanced to 88.56%. The total recovery of gold is 81.55%. |
| Keywords: | gold ores particulate dissemination bearing arsenic-containing floatation fine grinding intensified alkaline leaching pretreatment cyanidation |
