The effect of rotor speed on the flash flotation performance of Au and Cu in an industrial concentrator

The effect of rotor speed on the internal flow regime of the cell has been demonstrated through the use of axial profile data and profile normalisation. This has allowed a visual representation of the effect of increasing power input into the slurry and the consequent changes to turbulent flow. How this impacts both the internal classification profile of the machine and the size based performances of the target elements (Au and Cu) is discussed in detail. 3D interpretation of the effect of rotor speed on the size based recovery of Au and Cu within the machine are presented, and are the first such representations to be made for real data obtained from within an operating industrial scale flash flotation machine.
