Testing a flotation column at the Sarcheshmeh copper mine

Jul 01, 2001· The flotation circuit of the Sarcheshmeh copper mine, which processes 40,000 t/d of ore at 0.9% Cu, consists of rougher, cleaning and recleaning stages. Mechanical flotation cells are used in all stages. To investigate the amenability of flotation columns in the plant especially for cleaning and recleaning stages, a column was designed

Separation efficiency improvement of a low grade copper

The copper flotation circuits upgrade copper content by a with an additional dilute cleaning stage, and in all cases, high copper recoveries were achieved after four concentrates with a cumulative flotation time of 9-10 minutes used in each test. For all the streams tested, it was possible to reject greater than 20% of the

Mineralogical Prediction of Flotation Performance for a

That means that the copper-bearing particles are initially recovered, followed by carrollite in later stages of the flotation process. For cobalt, the maximum final grade was observed for sample S9 with 13.0% Co and a cobalt recovery of 66.5% while the highest final recovery was observed for sample S8 with 74.4% cobalt recovery and a final

Novel treatment for mixed copper ores: Leaching ammonia

Apr 01, 2020· Soluble copper diminished under the operational conditions from 0.38 to 0.035%, so attaining sulfurizing the ore, it was possible to proceed to the next flotation stage. • The better performance was achieved with SF-323 (15 g/t), SF-114 (40 g/t), and MIBC (55 g/t), giving a grade of copper concentrate of 12.9%, and 80% of recovery.

Coarse-particle flotation applied to copper sulfide ores

The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).
