Abstract: Introduced the effect of sulphur and sulfate on the alumina production.Typical high-sulfur bauxite desulfuration methods such as reverse-flotation desulfuration，electrochemistry desulfuration，chemical desulfuration and microorganism desulfuration were elaborated.Relative merits and development direction of desulfuration method were deeply analyzed.Research indicate that microorganism desulfuration will be most promising desulfuration technology of high-sulfur bauxite.

Key words: High-sulfur bauxite, Reverse-flotation desulfuration, Electrochemistry desulfuration, Chemical desulfuration, Microorganism desulfuration
