gold extraction from fine carbon Gold Refining Forum

04-02-2014· Oh! yeah,from the ashes, also mercury on carbons isn't good way cause mercury is adsorbed to carbon in normal temperature. Gold extraction from the ashes by cyanide is much much cheaper in cost than mercury amalgamation. We have a big gold plant with CIL( carbon in leach) process and our capacity is 3500 mtons ore per day and about 10-11 kg gold.

Gold extraction Wikipedia

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
