    Gold Cyanidation Process

    A common Cyanidation Process for Gold or called160 CIL 160and CIP. The amount of these two reagents in the slurry is very important without enough cyanide to consume all of the valuable mineral there will be losses. Without enough lime a condition may developed that could potentially be very haardous to the workers well
