The PTMS Electromagnetic Separator beneficiation process of removing fine iron impurities in kaolin is mainly to make raw ore, add dispersant for selective dispersion, and then Settlement separation. After separation, the lower pulp is added with dispersant for the second settlement separation, and the upper suspension of the two subsidence separation is added with flocculation for selective flocculation. Or pulp after adding dispersant dispersion, and then add flocculant, secondary selective flocculation separation.
Selective dispersion-flocculation process. In the PTMS Electromagnetic Separator process, kaolin raw ore (coarse concentrate after hydrocyclone sorting) is added water to make a solid slurry of about 10%, and then dispersant is added to fully stir and disperse, and the amount of dispersion agent is 1.0-3.0 kg per ton of kaolin.
PTMS Electromagnetic Separator Mineral processing process can use water glass, sodium hexadetaphosphate, sodium polyphosphate or sodium humate as a dispersant, among which sodium polyphosphate, sodium humate selectivity is good. When used alone, the best dosage of various dispersants is about 3200 g / ton, sodium hexadaphosphate about 2300 g / ton, sodium polyphosphate about 2200 g / ton, and sodium humate about 1100 g / ton.
