Abstract:
     The present invention relates to a bauxite coarse-fine sorting floatation desilicification method. Said method includes the following steps: firstly, grinding raw bauxite to obtain bauxite raw ore pule, sorting said ore pulp into two portions of coarse ore and fine slime, then using normal floatation technique to treat fine slime and using reverse floatation technique to treat coarse ore so as to implement optimization of bauxite floatation separation desilicification process to raise floatation index.
