metallurgically. CIP and CIL circuits are tolerant of plant upsets, changes in feed composition and less than optimal plant designs. As a result, owners and operators may not realize that their plant design could be less than optimal. The gold extraction is usually good enough and the economic payback is very good,
Importantly, the solution is also scalable and can support miners of various sizes and budgets. With the cost to invest in an entry level CiP/CiL plant upward of US$20 million, the solution potentially removes the cost barrier that prevents many miners from proceeding to production, as well as supporting small scale artisanal miners and co ops.
plant and/or full scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.
CIP 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.
A plant evaluation on a 180 000 t/month CIP plant was. ... Adsorption plant design. ... processes became firmly established in the gold mining industry in the 1980s, initially in South Africa and ...
Carbon in pulp 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.
