Optimizing Flotation Circuit Recovery by Effective Stage ,

the flotation circuit configuration is not very se nsitive to stage recovery [9,19 ] The overall output suggests that choosing the best flotation circuit is not sensitive to the stage recovery, and as a result, only approximate values of the recovery can be used to select the optimal flotation circuit [6,9 ,20 ]
