Rcovery of gold in pyritic ores

2013-1-13 · Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...
