Flotation cell turbulence

Aug 01, 1987 Turbulence in flotation cells. Int. J. Miner. Process., 21: 1-23. It is known that turbulence plays an important part in the operation of a flotation cell. Rota- tional speed and thus intensity of turbulence has a strong influence on the recovery and grade of concentrate of single cells and cell

    Oct 14, 2015 Since turbulence in a flotation cell varies significantly across the cell's cross-section, a turbulence measurement device needs to be able to perform measurements at a series of positions, not just an average over a cross-section. What is therefore required is an intrusive probe instead of the usual application of electrodes fixed to the walls
