Electromagnetic Separation for Quartz Processing line

The dried quartz sand is added to the immersion tank, and the acid (sulfuric acid, hydrochloric acid or hydrofluoric acid) is added quickly under drying and high temperature, the concentration of acid is 5% -20%, constant temperature stirring at 30℃ -100℃ for 2-24 hours, remove the trace metal and non-metallic impurities in quartz sand fine powder; acid immersion is one of the important processes of high purity quartz sand purification PTMS Electromagnetic Separator,

PTMS magnetic separation


The PTMS Electromagnetic Separator process must be used for the preparation of quartz glass for electric light source or quartz raw materials for photovoltaic and semiconductor devices. Wash the residual flotation agent and impurities on quartz sand surface; acid immersion is mainly to remove soluble metal oxides and some silicate minerals and trace impurities such as soluble aluminum and iron in minerals.

what is magnetic separation?


After roasting water quenching, picking and PTMS Electromagnetic Separator selection, most oxides and impurity minerals have been removed, but some oxides and impurity minerals are in the grain boundary, microfissure and crystal, so it is difficult to remove. Therefore, long-time acid leaching is used to remove such impurities.
