Improving the recovery of gold and copper in a CIP

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%.

Gold CIP Processing,Gold CIP Plant,Gold CIP Production

CIP (Carbon in pulp) process is a high efficient method to leaching and recovering gold from gold ore, The most different from CIL process is in CIP process, gold leaching and adsorption are separated, first leaching, and then adsorption. Now it is being replacing by CIL process progressively. But it still have a lot of application.

Gold CIL & CIP Gold Leaching Process Explained CCD

02/01/2013 Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitated tanks containing activated carbon.

Electrowinning of gold copper ores Hydrometallurgy

The copper content is not high enough for economic recovery but its high enough to cause problems in our CIP circuit and electrowinning. A typical elution would produce about 4kgs of gold and 5kgs of copper. The copper makes it difficult to strip the gold off the steel mesh cathodes. Which would be the best stage to eliminate copper, during cyanidation, adsorption or electrowinning. And how do
