Abstract
Madneuli copper enrichment plant works since 1975. This plant works on copper sulphide ores from Madneuli and Sakdrisi deposits. In some ores due to difficulties of blotting secondary copper sulphides, recovery of copper in commercial production is low – 60-65%. At the same time, concentration of copper in tails is 0.17-0.19% and concentration of gold in tails 0.3-0.6 gr/t. In this article we consider combine technology of processing rich flotation tiles: preinrichment by gravity (use centrifugal concentrator and/or short noise hydrocyclone). Gravity concentrate with au and cu 5.47 gr/t, and 0.93%, respectively proceed hydrometallurgicaly (cyanidation) this technology makes possible rise recovery of gold and copper in commercial product by 20-25% and 17-20%.
