uses of flocculation for mining

  • Two-stage shear flocculation for enrichment of fine boron

     · Shear flocculation and two-stage shear flocculation experiments. The shear flocculation experiments were carried out in a 400 cm 3 cylindrical cell with four baffles using 1 g solid and 300 cm 3 water. The mixture of solid-water suspension was pre-conditioned for 1 min in order to obtain a well-dispersed suspension.
