Us3920403a Method Of Desorbing Gold From Activated

Gold in the form of its cyanide complex is desorbed from activated carbon by contacting the carbon with a stripping liquid at temperatures above that 130C but below the decomposition temperature of the gold cyanide complex. The stripping liquid may comprise water, dilute caustic or dilute caustic cyanide.

Damang Gold Mine Mining Technology Mining News And

For short-term ore supply, while the pre-strip is in progress, mining activities will continue at the Amoanda and paleaoplacer satellite pit, while ore will also be received from low-grade surface stockpiles. A total of 165Mt of ore will be mined, with 32Mt processed at a grade of 1.65gt during the lifetime of the mine. Gold ore processing

Separating Copper From Gold Electroplating

But the cold strip works up to a certain limit that should have been detected with proper mineralogical characterization. If the amount of copper is such that the ore really corresponds to low grade copper with traces of gold , then a copper removal step employing for instance the SART process might be mandatory, in addition to the cold strip.
