Magnetic separator manufacturer

Iron exists in the form of strong magnetic magnetite, which can be removed effectively by ordinary magnetic separation method and with low content, high gradient PTMS Electromagnetic Separator or chemical leaching method can be considered. Acid leaching (such as oxalic acid leaching) may be a better choice, but if kaolin contains iron sulfide minerals, ilmenite, etc.

PTMS magnetic separation

A kaolin is mainly goethite and limonite impurities, using high gradient PTMS Electromagnetic Separator + chemical bleaching process, magnetic induction strength of 1.4T, dispersant dosage of 2kg / t, bleaching pH value of 3, insurance powder dosage of 4%, reduction time of 30min, oxalic acid dosage of 4%, improve the white degree of kaolin from 60% to 75.63%.

what is magnetic separation in chemistry？

When iron exists in an insoluble state and requires high whiteness of kaolin, chemical bleaching can be used as a means of further purification, but attention should be paid to control the cost and reaction conditions. The whiteness of the kaolin was improved by removing some of the magnetic iron minerals by PTMS Electromagnetic Separator, followed by further removing the remaining iron impurities by chemical bleaching.
