  • FLOTATION LAUNDER DESIGN, DOES IT MATTER?

    There are two key factors at play when deciding the flo- tation equipment selection for your circuit viz. residence time and froth transport parameters. Both are highly dependent on the specific ore characteristics such as mineral grade, liberation, flotation kinetics and specific gravity.:: Selecting Flotation Cells: How Many and What Size?,The difference in performance between 5 cells and 8 cells with equivalent residence time cannot be detected in most cases due to noise from other flotation factors. When consideration is given to capital and installation cost, plant footprint and operability the economic solution is generally less than 8 cells.
