Use in Mining | International Cyanide Management Code (ICMI

The gold and/or silver adsorbed on the activated carbon is recovered from the carbon by elution, typically with a hot caustic aqueous cyanide solution. The carbon is then regenerated and returned to the adsorption circuit while the gold and/or silver is recovered from the eluate using either zinc cementation or electrowinning.
