Before iron removal in kaolin, the phase composition and embedded structure characteristics of iron must be determined first, which is the basis for selecting the process of PTMS magnetic separation iron removal. The iron impurities in kaolin are generally divided into free iron and structural iron. Free iron is usually independent iron minerals, including magnetite (Fe ₃ O ₄), hematite (Fe ₂ O ₃), limonite (Fe₂O₃ nH₂O), siderite (FeCO ₃), pyrite (FeS ₂), etc.

PTMS magnetic separation

Almost all kaolin raw minerals contain a small amount of iron minerals, mainly iron oxide, ilmenite, siderite, magnetite pyrite, mica, calcium carbide, etc., these colored impurities usually have weak magnetism. Therefore, according to the magnetic difference between hematite, hemite and magnetite gangue minerals and kaolin, they can be removed by PTMS magnetic separation.

how to separate two magnets？

For strong magnetic minerals such as magnetite, the ideal effect can be obtained by using weak magnetic separation method. For weak magnetic minerals, high gradient strong magnetic field PTMS magnetic separation should be used, this method can effectively remove weak magnetic fine particles and even colloidal particles in useful minerals, and separate micron level paramagnetic materials.
