A Technology of Gold Recovery from Carbonaceous Ores

摘要：

To improve gold recovery from preg-robbing carbonaceous ores a technology including gravity,flotation, recleaning of the flotation concentrate, intensive cyanidation of the gravity concentrate and carbon-in-leach (CIL) process for intensive cyanidation tailings and the recleaned concentrate was developed. The final flotation tailings are shipped to tailings disposal.Total gold recovery by the proposed technology from the ore with the head grade of 0.8 g/t was 83.9%. The gold loading onto the activated carbon from CIL process was 6.5 g/kg.
