Optimisation of a multistage flotation plant using plant

Conventional models, based on pulp kinetics, were regressed directly to steady-state data from a nine-stage platinum flotation plant, to provide a basis for optimisation studies ‘Froth factors’ were obtained by regression to characterise the froth in each stage and a ‘depressant factor’ was also required for gangue minerals, to account for effect of additional depressant in the cleaners
