Leachwelltm In Cyanide Soluble Copper Assays

Red Dome Gold Mine classifies ore types within the pit by gold and copper grades. Copper grades are further distinguished by total copper and cyanide soluble copper levels. At present, Cyanide Soluble Copper samples take six hours of agitating before they can be assayed. This agitation time produces results which are a proportion of the total cyanide amenable copper. This relates to our plant's performance. Frequently the total copper result is needed before we can begin the cyanide soluble copper analysis. This caused a protracted tum around time. Mennetech Pty. Ltd has produced a catalyst proven by David Martin Menne to accelerate the cyanidation of gold. David said that the information at hand indicated that Leach WELL TM also accelerates the leaching of cyanidable copper substantially. Test work was undertaken on-site at Red Dome Gold Mine to investigate the potential of Leach WELL TM to reduce the leaching period and therefore, the overall tum around time required for cyanide soluble copper determinations.
