cyanidation process with ore extraction optimal performance in nigeria

Additionally as the copper content of the ore was about 800 times more than its gold most of the free cyanide ions will be utilized in the copper dissolution process and inhibit Au extraction Therefore it will be helpful to leach the copper content of the ore before starting biocyanidation
