The invention discloses a method for separating bauxite and sulfur-containing ore from high-sulfur bauxite, comprising the steps of finely grinding and floating bauxite containing high sulfur, floating ore concentrate and concentrating to obtain qualified bauxite with low sulfur for extracting alumina and simultaneously obtain qualified sulfur-containing minerals with high sulfur content. By the method, the bauxite containing high sulfur can be well utilized by using a simple floating process with low cost before the bauxite is dissolved out, the bauxite and the sulfur-containing minerals canbe comprehensively utilized and the recovery rates of alumina and sulfur are high; and the invention has the advantages of low cost, simple and convenient process, safety, environmental protection and the like.
