Capital Prize Gold Mine Gold Processing

Cyanide leaching is the standard method used for recovering most of the gold throughout the world today The process originated around 1890 and quickly replaced all competing technologies The reason was strictly economical in nature Where amalgamation plants could recover about 60 of the gold present cyanide could recover about 90

Gold cyanidation Wikipedia

Eisner s equation is generally accepted as expressing the action of gold in dilute cyanide solutions 4 Au 8 KCN O2 2H2O 4 KAu CN 2 4 KOH Thus when fresh surfaces of gold are exposed to the action of cyanide in an aqueous solution containing free oxygen a gold cyanide compound will be formed and a hydroxide alkaline

Elution and Carbon Reactivation Resource book

During the CIL process gold is leached from the ore using an alkaline cyanide solution The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon Elution is the next step in the process whereby the adsorption of the gold cyanide complex onto carbon is reversed
