Abstract:In the face of the shortage of high-quality bauxite resources in China, the utilization of complex high-sulfur bauxite resources will help to ensure strategic safety of bauxite resources and sustainable development of alumina industry. The reserves of high-sulfur bauxite are abundant in China, but it cannot be used efficiently because of the hazards of sulfur to the Bayer process. The research status and technical level of high-sulfur bauxite desulphurization methods such as flotation method, roasting method and dissolution desulfurization were summarized, and the future research direction and development trend were prospected.
