What acid solution is used in the highly effective PTMS magnetic separation process of iron removal in kaolin

Magnetic magnetic separator
PTMS magnetic separation Process: the initial pulp and sand removal in the existing technology is transferred to the mixing tank, and the acid solution is added to adjust pH = 3 to obtain the pickling material. Among them, the weight ratio of kaolin to water in the initial slurry is 1:4, the stirring speed in the mixing tank is 250 r/min, and the stirring time is 15 minutes;
PTMS magnetic separation
The acid solution is sodium bisulite solution, and the mass ratio of sodium bisulite solution and the first material of kaolin slurry is 1.5:100. Grade the pickling material to the PTMS magnetic separation cyclone and continuously feed the cationic flocculant to the pipe before the pickling material to the cyclone,
what is magnetic separation method?
The concentration of cationic flocculant in the pickling material is 4ppm. After the pickling material is graded by the hydrocyclone, the upper pickling waste liquid and the lower pickling slurry are obtained. Continue to pour water into the bottom pickling slurry, and send the water and the bottom pickling slurry to the PTMS magnetic separation hydrocyclone for three times, to get the top cleaning waste liquid and the bottom cleaning slurry.
