The paper presented outlines the scientific approach taken to improve the metallurgical efficiency of a modern plant at Athens Mine. The plant is based on the CIP method of gold recovery with copper concentrate as a major by-product. In the early stages of the operation the overall gold recovery achieved averaged 61% and copper recovery was 74%.
Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold's hydrophobicity. First, refractory gold ore is ground as finely as possible usually so the individual ...Chat Now
