Rcovery of gold in pyritic ores - Mine Engineer.Com

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 ...

Gold extraction - QueensMineDesignWiki

2019-6-28  Reactive sulphides containing gold, such as pyrrhottite, can require high amounts of oxygen as the iron (II) is oxidized to iron (III), and sulphide to sulphate (Brooy, 1994). Oxidant addition is employed in these cases to meet oxygen demands, and can be controlled by an oxygen electrode inserted into the leach tank.
