water cooling electromagnetic separator for Quartz

For some kaolin, either oxidation or reduction can not achieve satisfactory results, so it is necessary to bleaching it by oxidation-reduction combined PTMS Electromagnetic Separator. With the development of science and technology, the whiteness of kaolin is more and more demanded by ceramic industry and other industrial departments, and chemical iron removal bleaching method will be more widely used.

PTMS magnetic separation


The PTMS Electromagnetic Separator process is to oxidize and remove chromic matter and pyrite in kaolin by strong oxidizing agents sodium hypochlorite and hydrogen peroxide, and then reduce bleaching by sodium dithionite. The remaining iron oxides in kaolin, such as Fe2O3 and FeOOH, are reduced to soluble bivalent iron and removed, so that this kind of kaolin is bleached. The finishing process of kaolin must go through a series of processes such as purification classification, stripping, magnetic separation and chemical bleaching.

what is magnetic separation in chemistry?


Due to the relatively high cost of chemical bleaching process, it is necessary to make full use of the previous several processes to beneficiate kaolin, PTMS Electromagnetic Separator to remove iron, and then chemical bleaching, in order to minimize the amount of pulp processed by the bleaching process and reduce the amount of bleach.
