Cyanide Chemistry International Cyanide Management

High copper concentrations in the ore increase costs and lower recovery efficiencies by requiring higher cyanide application rates to compensate for reagent that complexes with copper rather than gold. Cyanidation is also adversely affected by the presence of free sulfur or sulfide minerals in the ore.

Recovery Rate Definition Investopedia

Jul 14, 2019What is 'Recovery Rate'. The recovery rate enables an estimate to be made of the loss that would arise in the event of default, which is calculated as (1 Recovery Rate). Thus, if the recovery rate is 60%, the loss given default or LGD is 40%. On a $10 million debt instrument, the estimated loss arising from default is thus $4 million.

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.
