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 ...

Evidence supporting micro-galvanic coupling in sulphides ...

2021-3-12 · Electrical micro-junctions in metal sulfides drive electrochemical reactions with passing gold-bearing fluids, resulting in the deposition of gold, even from under-saturated ore fluids. Understanding the role micro-junctions play in the deposition of gold requires (a) imaging the electric field distribution of a galvanic couple near the surface to qualify the existence of an active micro-geo ...

how do i separate gold from sulphides without using

gold mining micron gold and sulphides - crusherasia. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in

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.
