Based on the characteristics of China\'s bauxite and cyclone separation,the cyclone-reverse flotation technique was experimentally carried out for the separation of low-grade bauxite,of which the w(Al2O3)/w(SiO2),abrasive size and mass fraction are 4.

The paper puts forward a new kind of slurry water disposal process that floatation cyclone and slime centrifugal screening mill are used as key equipment.
