Rcovery of gold in pyritic ores

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.

Galena

 · The flotation tailing from the lead section passes to a wet cyclone to make a primary sand-slime separation. The cyclone overflow passes to a Hydroclassifier which is operated to overflow a turbid overflow which contains the minus 20 micron slimes. This step is often necessary to remove the fine slimes which interfere in the flotation of the.

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of.
