A review of froth flotation control

This has allowed a flotation cell to be modelled using the chemical reactor analogy; whereby the removal of solids from the pulp phase is defined by a first order rate equation. This means a bank of cells can be approximated by perfectly mixed CSTR's in series (Gaudin, 1957, Niemi and Paakkinen, 1969, Atkins et al., 1986, Yuan et al., 1996).
