Abstract
High content of silica results in high soda consumption, which limits the use of high-silica bauxite in the production of Bayer alumina. In this work,the main flotation parameters of high silica bauxite (A/S 5.0) including particle size, pulp pH, collector dosage and dispersant dosage were studied. With an optimal condition of 33% solid density, particle size of -74 μm above 93%, sodium oleate dosage 2200 g•t−1, Na2CO3 dosage 2000 g•t−1, sodium hexametaphosphate dosage 30 g•t−1, slurry pH 9.4 and agitation speed 2280 rpm, the recovery of aluminum minerals of 56%, the A/S of concentrate of 12.2, and the separation index of 0.4 can be obtained.
