Abstract:
     A floatation process for bauxite to remove S and Si includes such steps as grinding the crude bauxite, adding the yellow catching agent B, reverse floatation for removing S, grinding, adding the match of saponified fatty acid and naphthenic acid, and forward floatation. The resultant bauxite concentrate can be used to prepare aluminum oxide by Bayer method.
