Outline
Based on the mineralogy of the high-sulfur sedimentary bauxite ore from Pingguo area of Guangxi, including mineral composition, structural property and mineral dissemination characteristics, three kinds of technical schemes were proposed according to the ore properties, including flotation, reduction roasting plus magnetic separation, and calcination, and then adopted respectively in experiments of desulfurization. The mineralogical study shows that this bauxite ore contains 65.04% Al2O3 with S grade of 5.08%, and the dominant minerals therein are diaspore and pyrite. It is found that the pyrite can be effectively removed by those three processing techniques, and the flotation process can yield an bauxite concentrate with Al2O3 grade of 75.90% and the S grade reduced to 0.49%, which is qualified as the feed material for the succeeding alumina extraction. In this case, it is recommended that the flotation be selected as a pre-desulfurization solution for high-sulfur sedimentary bauxite ore.
