The gold ore is double-refractory. First, the gold is locked in sulfide mineral particles that must be oxidized to expose the gold for leaching. Second, the ore also contains preg-robbing carbon that will collect solubilized gold from the subsequent leaching circuit if the gold is not first removed.

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low …
Material feed into the hopper by excavator,high pressure water released and wash the mineral,then,mineral by forward into the drum.It is lifted up by the rotation and aerated as it fall back down.This finer material passes through the screen openings while the large material tumbles towards its eventually exit at the real of the drum.After that,the final …
In the case of cyanidation plants processing gold ores with metallic sulfides, oxygen is not only used to optimize plant throughput but also to enhance gold extraction. Because the dissolution of sulfide minerals consumes oxygen ( (26.8), (26.10), (26.11) ), it is important to avoid a reduction in the gold-leaching rate associated with low DO ...

Low-grade gold ore: If the gold ore has a low grade, that is, the metal content is low, the gold concentrate obtained after processing will be correspondingly low. This means that the gold concentrate contains less metal, and the recovery rate of gold and the efficiency of gold smelting will be reduced accordingly.
