flotation separation for copper tailings

The actual experimental test work was performed using the Knelson gravity concentrator and the results were transposed to industrial scale by simulating several beneficiation scenarios. The results indicated that integration of Knelson concentrators in the concentration circuit to treat the flotation tailings would significantly improve copper and cobalt recoveries from65.00% to 86.09% and 67.00% to 86.96%,…
