PTMS magnetic separation Iron removal and whitening process plays an important role in kaolin processing
Magnetic separator
With the decrease of high-quality kaolin resources (Fe2O3 content <1.0%), most of the high-speed railway kaolin (Fe2O3 content> 1.10%) is abandoned by "dull ore", which cannot be fully utilized temporarily, resulting in a waste of resources and can be used after iron removal. Due to the different causes and types of kaolin, the composition and content of its iron are also different, and the required PTMS magnetic separation iron removal process is also different.
PTMS magnetic separation
Therefore, in order to obtain the whitening of kaolin and revitalize the "dull mine" kaolin resources, PTMS magnetic separation iron removal whitening process is particularly important in the processing process of kaolin processing. Chemical iron removal methods are widely used, and chemical reagents such as bleach are mostly used, but there are disadvantages such as high production cost, corrosion equipment, environmental pollution and complex operation skills.
what is magnetic separation?
At present, the PTMS magnetic separation to improve the whiteness of kaolin has physical methods (including hand selection method, water separation method, magnetic separation method, flotation method), chemical methods (including oxidation method, reduction method, oxidation reduction method and other methods), the latest methods at home and abroad are microbial iron removal method, organic acid iron removal and whitening method, etc.
