The open-pit and underground mines supply both course gold and refractory ore to a processing plant that includes crushing, grinding, gravity recovery, flotation, oxidation (autoclave) and Carbon In Pulp (CIP) circuits to produce a gold dore product and a high grade pyrite concentrate for shipment to offsite refineries and smelters for final ...
AngloGold merged with junior partner Golden Cycle Gold Corporation in 2008 and thereby acquired the remaining 33% of the project. The mine is a low-cost, low-yield open pit operation, with grades well below one gram of gold per tonne of ore. In recent years, 2008 and 2009, the mine accounted for 5% of AngloGold Ashanti's worldwide production.

Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...
