how separate gold from chalcopyrite
Four Major Flotation Separation Processes to Separate ...
2021-2-1 · Chalcopyrite is a widely distributed copper-iron sulfide mineral, often containing trace amounts of gold, silver and other minerals, and is the main copper-containing mineral. With the deepening of mining, low grade polymetallic refractory chalcopyrite has become an important source of copper ore. Now, let’s know the common chalcopyrite flotation processes together.

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 ...
