Copper contamination of gold cyanidation circuits causes a number of problems in gold processing (Sceresini, 1999). Copper oxide minerals (i.e. azurite, malachite, cuprite, tenorite) have fast leaching rates in cyanide. Secondary copper sulphide minerals such as chalcocite and covellite leach rapidly

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are …

The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.
