water cooling electromagnetic separator for Feldspar

Take kaolin raw materials and appropriate amount of dispersant and add water to prepare a slurry with kaolin content of 40wt %, stir fully, and obtain a thin slurry with kaolin content of 5wt %; The dispersant was sodium hexametaphosphate and the added amount was 5mg/l. Add insurance powder to the thin stock, and adjust the ph of the stock to 7.5; The stirring time was 120min and the reaction temperature was 40℃. Among them, the amount of insurance powder is 1% of the quality of kaolin sample. PTMS magnetic separator can improve the whiteness of kaolin products.

PTMS magnetic separation

The ph of the slurry was adjusted to 1.5, and 1% oxalic acid of kaolin sample was added. The reaction temperature was 40℃, and the stirring time was 120min. After filtration, washing and drying at 105℃, the kaolin product is obtained by PTMS magnetic separator after first whitening. After the first whitened kaolin product is crushed, water is added to prepare a slurry with a concentration of kaolin and a content of 5wt %;

what is magnetic separation used for？

Add sio2 with 5% kaolin mass and naoh with 20% kaolin mass at 60℃, continue stirring and reaction for 20min, add h2so4 solution with 50% kaolin mass at a constant and slow speed, sink, filter, wash, and dry at 105℃. PTMS magnetic separator The whitened kaolin is obtained.
