| Abstract: | A simple empirical dimensionless model to calculate the mineral gangue recovered per size class (RG,i) by entrainment, in terms of the water recovery (RW), in an industrial flotation cell is presented. For modeling purposes, a dimensionless entrainment factor EFi, corresponding to the ratio (RG,i/RW), was defined for each particle size class. From experimental data measured in an industrial 130 m3 flotation cell, it was found that EFi was well correlated with the dimensionless ratio (dP,i/δ) by |
