Abstract：The desulfurization of high-sulfur diasporic bauxite from China with flotation process and butyl xanthate as collector was studied, and the effects of flotation time, pulp density, pH value and particle size of ores on the desulfurization rate were examined. The results indicated that the sulfur in bauxite was successfully decreased through flotation. The sulfur content was lowed to 0.41% under the conditions of pH value at 10, the dose of flotation agent butyl xanthate 0.16 kg/t, frother 20 g/t, flotation time 15 min, mass ratio of liquid to solid 10, the particle size of ores 0.15 mm, and the reclamation of Al2O3 was 90.83%. The kinetics of flotation desulfurization was also studied. The flotation obeyed the first order kinetic equation.
