flotation scale up use of separability curves sciencedirecttime scale up factors for flotation kinetics prediction are generally derived by comparison of industrial flotation banks and laboratory batch cell recovery. however, in plant practice it is common to find very low mineral recoveries in the last cells of the rougher banks.

considerations in mineral processing of scaleup from a series of batch flotation test were used to evaluate the behaviour of main ore minerals (copper, zinc). obtained data was used to create floatability component models that were further applied in simulation by hsc chemistry 7.1 to give a forecast of grades and recoveries in full scale production.
