PTMS magnetic separator improves the effect of removing iron and brightening low grade kaolin
Mineral processing equipment
Because the settling of kaolin requires a long standing time and needs to settle several times before iron removal is qualified, the iron removal efficiency is very low. On the other hand, after using this method, the slurry will occupy the storage tank or tank for a long time during the static process, resulting in the subsequent slurry can not normally flow into the storage tank or tank, reducing the production efficiency of kaolin. PTMS magnetic separator solves the above problem.
PTMS magnetic separator
The dispersant is sodium carbonate, sodium silicate or sodium hexametaphosphate, and the addition amount is 5mg/l ~ 25mg/l. The amount of urea SO2 was 1%-5% of the mass of kaolin. The range of ph adjustment is 7.5 ~ 9.5; The stirring time was 30min and the reaction temperature was 40℃ ~ 90℃. The range of ph is adjusted to 1.5 ~ 3.5, the stirring time is 30min, and the reaction temperature is 40℃ ~ 90℃. These operations are conducive to the removal of iron by PTMS magnetic separator.
what is magnetic separation in Feldspar?
The amount of oxalic acid is 1% ~ 5% of the quality of kaolin sample. The drying temperature is 105℃. The amount of sio2 added is 5% to 20% of the quality of kaolin after the first whitening. The addition amount is 20% ~ 60% of the quality of kaolin after the first whitening. The drying temperature is 105℃. Through multi-step treatment, PTMS magnetic separator can improve the iron removal and whitening effect of low-grade kaolin, and increase the whiteness of the final product by 30% ~ 50%, realizing efficient whitening effect.
