gold extraction from fine carbon Gold Refining Forum

Feb 04, 2014· Dear Sucho, It is cyanide-gold complex that was adsorbed to carbon in our gold plant. These are the fine carbones that came out from the process duo to the small size. The best way for the extract is burning the carbon then leach the ashes by cyanide again and extract the gold and silver. as the carbons are hard the burning as also hard.

Carbon Adsorption In Recovery Of Gold Mine Engineer.Com

The carbon is then cooled, screened to remove fines and is ready for reuse. Fines are not desirable in carbon circuits, since they will escape through the carbon screens and end up in the leach, capturing gold that will not be recovered. For this reason, high quality and hard carbon is generally utilized for these applications.

Carbon Stripping Denver Mineral Engineers

carbon as a sodium or calcium/gold cyanide ion pair (2) is desorbed from the carbon by a reversal of the adsorption kinetics. Gold is recovered from the pregnant strip solution by electrowinning onto steel wool. The gold depleted solution is then reheated and recycled to the carbon bed for reuse (see Figure 1).
