The response of diasporicbauxite flotation to particle

This paper was to investigate the effect of particle size on diasporicbauxite flotation. For this purpose, concentrate products of various size fractions were collected at different flotation times and forwarded to the testing of Al 2 O 3 and SiO 2 contents. Six flotation kinetic models were applied in the fitting of the experimental data in terms of Al 2 O 3 and SiO 2 recovery.
