Flotation Desulfurization of High-Sulfur Bauxite with Ethyl Thio Carbamate as Collector

Abstract:

The desulfurization of high-sulfur diasporic bauxite （from China） with flotation process and ethyl thio carbamate as collector was studied, and the effects of flotation time, pulp density, pH value and particle size of ores were examined. The experimental results indicate that the sulfur in bauxite was successfully decreased through flotation. The sulfur content of bauxite was lowed to 0.66% under the condition of pH value 4, the dose of flotation agent ethyl thio carbamate 0.5kg/t, frother 20g/t, flotation time 15 minutes, pulp density 10%, the particle size of ores ≦0.09 mm, and the reclamation of Al₂O₃ is 90.16% as well. The flotation kinetics of flotation desulfurization was also studied.
