The lower layer was washed into the alkaline solution to pH = 7 and then to PTMS magnetic separation. Ferric ions are easy to form colloids under alkaline conditions, so controlling the ph of the pulp first material between 2.0 and 5.0 so that most of the ferrous ions can exist in the pulp first material and will not be hydrolyzed.

Then to the pickling into the cation flocculant, cation flocculant of pickling in suspension particles (kaolin) have strong flocculation settlement effect, especially for negative charge of colloidal solution particles more shows its superiority, and ferrous ions with positive charge, so ferrous ions will remain dissolved in water, is advantageous to PTMS magnetic separation in addition to iron.

what is magnetic bead separation?


Then pickling material after PTMS magnetic separation hydrocyclone after the upper pickling liquid and lower acid slurry separation, including the upper pickling liquid with a large number of iron ions, and the lower pickling slurry for kaolin pulp, because most of the iron ions in the upper pickling waste liquid, so kaolin pulp with iron ion quantity greatly reduced.
