Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately.Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.

A clean hydrometallurgical process has been developed to efficiently and economically recover selenium, copper, gold, silver and lead from a copper anode slime.The mixture of h 2 so 4 and h 2 o 2 was demonstrated to be effective for selenium leaching based on their synergistic effects, and the potential synergy mechanism was proposed.Get Price
The copper is initially recovered from the concentrate using the cesl copper process robinson, mayhew, jones, murray, 2011.The gold and silver remain in the leach residue, which is subsequently treated using the cesl gold process.The cesl gold process consists of the following main steps as illustrated in the figure below.Get Price
A study of the influence of copper on the gold electrowinning process by j.Steyn and r.F.Sandenbergh paper written on project work carried out in partial fulfilment of b.Eng metallurgical engineering degree synopsis electrowinning is an attractive method to recover gold from the relatively concentrated aurodicyanide solutions.Get Price
The cesl gold-silver process was developed as an important value enhancing technology to recover gold and silver from residues produced from the cesl copper process or other hydrometallurgical processes.Residues from the cesl copper process contain small amounts of cyanide soluble copper as well as elemental sulphur.Get Price
