The mineral liquid was settled twice and then separated to PTMS magnetic separation iron removal process
wet high intensity magnetic separator
Mineral liquid will two settlement separation of upper suspension, add selective flocculant for selective flocculation, flocculant selective adsorption and bridge between kaolinite particles, form flocculation, can make kaolin and fine iron impurities separation, the lower flocculate as kaolin concentrate, the upper suspension for high iron content of tailings, PTMS magnetic separation iron process.
PTMS magnetic separation
With strong selectivity for kaolin coagulation, the coagulant is anionic polyacrylamide (molecular weight of 9 million) with hydrolysis ability of 26.2%, and its dosage is 3.0 g / ton. First, the kaolin ore adds water to make a solid slurry of about 10%. PTMS magnetic separation can remove the iron (FE2O3) in the kaolin. Add dispersant sodium polyphosphate 2300 g / ton or sodium phytate 500 g / ton and water glass 1800 g / ton for stirring dispersion (1 min),
what is magnetic separation in Kaolin?
Add flocculant anionic polyacrylamide (hydrolysis 26.2%, molecular weight 9 million), dosage of 1 g / ton for selective flocculation, flocculation and water (solid content is about 10%), then the second selective flocculation, flocculation, concentrate, two selective flocculation separation of suspension for tailings, then PTMS magnetic separation iron removal process.
