Abstract: | Abstract The role of processes operating in the mineralised froth encountered in production scale flotation machines is discussed in relation to both process operation and mathematical modelling techniques used for simulating process response on complex process flowsheets. The structure of froths (and associated drainage patterns) developed on a continuously operated flotation cell over a wide range of operating conditions is reported. The concept of shear induced drainage in the froth is introduced, where mobility in froths on producing cells is seen to reduce froth separation effects. The relation of shear induced drainage to modern cell design is discussed, particularly in terms of maximising froth separation effects to enhance process separation efficiency. |
