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%.
