Optimisation of gold recovery by selective gold flotation

At high pH, selectivity of gold against pyrite was possible with a number of collectors. However, there was no selectivity against chalcopyrite in the flotation tests performed. Increasing the pH using lime showed no gold depression. Fine gold was easily floated while some coarse gold reported to the flotation

Silver Gold Recovery Flotation Process 911 Metallurgist

Oct 17, 2016· Both gold and silver may be present, the gold values being usually associated with chalcopyrite and pyrite, and the silver with galena and tetrahedrite. Flotation follows ordinary standard methods, modified as may be necessary to bring up the precious metals in the concentrates where they will be of most value.

A Review on Novel Techniques for Chalcopyrite Ore Processing

Jan 01, 2012· Valuable mineral in an ore such as chalcopyrite ore can be separated from each other and from worthless gauge minerals by the froth flotation process. The process was developed in Australia at the start of the 20 th Century to treat the primary sulfidic silver/lead/zinc ore at Broken Hill (Woods and Doyle, 2000).

surface properties. The flotation results indicated that cyanide chalcopyrite was strongly inhibited by sodium cyanide, with the maximum flotation recovery of 22.5% only. CuSO 4 and H 2 O 2 significantly improved the flotation of cyanide chalcopyrite, and the flotation recovery was increased to 92.28% and 84.35%, respectively.
