water cooled electromagnetic Separator for Silica Sand

Different PTMS magnetic separation are suitable for different types of kaolin and impurity conditions. Different catalysts also have varying effects in the iron removal process. Sulfuric acid can react with iron and other metal oxides in kaolin to form soluble sulfates, thereby removing iron impurities. Oxalic acid, on the other hand, has strong chelating ability and can form stable complexes with iron ions, separating them from the kaolin.

PTMS magnetic separation

Sodium metabisulfite is a strong reducing agent that can reduce trivalent iron in kaolin to divalent iron, thereby enhancing the whiteness of kaolin in PTMS magnetic separation processes. In practice, the process parameters for chemical bleaching need to be optimized based on the specific conditions of the kaolin. The dosage of chemicals, reaction temperature, and reaction time all affect the bleaching effect.

what is magnetic separation in Feldspar？

Generally speaking, excessive dosage of reagent will increase the cost, and may also PTMS magnetic separation have a bad effect on the structure and performance of kaolin; too high reaction temperature may lead to decomposition of reagent, reduce the bleaching effect; too short reaction time may make the reaction incomplete, unable to achieve the ideal whitening effect.
