The whiteness of kaolin PTMS Electromagnetic Separator process can be increased to 90%
eriz magnetic separator
The impurities are mainly goethite and limonite. Methods: High gradient PTMS Electromagnetic Separator + chemical bleaching process, the magnetic induction intensity was 1.4T, the amount of dispersant was 2kg / t, the bleaching pH value was 3, the amount of safe powder was 4%, the reduction time was 30min, and the amount of oxalic acid was 4%. Effect: The whiteness of kaolin increased from below 60% to 75.63%.
PTMS magnetic separation
Kaolin impurities: mainly calcium carbonate, and contains a small amount of iron and titanium impurities. Methods: For acid immersion, the liquid-solid ratio of kaolin mineral slurry is 6:1, the acid addition amount is 0.02mol, the reaction time is 10h, and the reaction temperature is 20℃. Effect: the PTMS Electromagnetic Separator whiteness of kaolin can be increased to 90.0%.
what is magnetic separation method for concentration of ore?
Kaolin impurities: mainly iron oxide. Methods: For the reverse flotation PTMS Electromagnetic Separator + reduction bleaching + calcination process, the reverse flotation pH value was 5.7, the reduced bleaching pH value was 2.3, the amount of safe powder was 3.3%, the amount of oxalic acid was 3.2%, and the calcination temperature was 1300℃. Effect: The whiteness of raw ore kaolin increased from 54.28% to 75.41%, and the whiteness was 89.69% after calcination.
