water cooling electromagnetic separator for Kaolin

The quartz sand with deionized water is dried (dried) to remove large quantities of water, then dried and PTMS magnetic separation iron in special drying equipment, and heated to 100℃ -200℃; add the dried quartz sand to the dipping tank, quickly add the acid (sulfuric acid, hydrochloric acid, nitric acid or hydrofluoric acid) under dry high temperature, the concentration of acid is 5% -20%,

PTMS Electromagnetic Separator

At constant temperature of 30℃ -100℃ for 2-24 hours, remove trace metal and non-metallic impurities in quartz sand fine powder; acid leaching is one of the important process of high purity wet beneficiation of quartz PTMS magnetic separation process, whether preparation of quartz glass for electric light source or quartz raw material for photovoltaic and semiconductor devices.

what is magnetic separation method ?

Acid immersion is mainly to remove metal oxides dissolved in acid and some silicate minerals, as well as trace impurities such as soluble aluminum and iron in minerals. After roasting water quenching, picking and PTMS magnetic separation, most oxides and impurity minerals have been removed, but some oxides and impurity minerals are in the grain boundary, microcracks and crystals, so it is difficult to remove, so long-time acid leaching is used to remove such impurities.
