magnetic separator for quartz sand

The chlorination roasting and PTMS ELECTROMAGNETIC SEPARATOR iron removal method is a chemical purification technique that uses chlorine gas at high temperatures to volatilize impurities from quartz sand. In the semiconductor industry, where purity standards for quartz sand are exceptionally stringent, this method remains the only viable solution. Researchers are continuously developing innovative acid washing agents and processes to reduce acid consumption and wastewater generation, thereby alleviating environmental pressures associated with acid washing techniques.

PTMS MAGNETIC SEPARATION

In quartz sand, impurities such as titanium and boron are particularly challenging to remove, as they significantly affect the purity and quality of the material. When exposed to high temperatures and chlorine gas, these impurities undergo chemical reactions with chlorine, forming volatile chlorides. These chlorides then disperse from the quartz sand through gas flow, effectively achieving the goal of impurity removal in the PTMS ELECTROMAGNETIC SEPARATOR process.

what is magnetic separation used for?

The chlorination roasting +PTMS ELECTROMAGNETIC SEPARATOR iron removal method can improve the purity of quartz sand to 6N (99.9999%), which is the core process of semiconductor-grade quartz sand purification. In the process of semiconductor chip manufacturing, quartz sand, as an important raw material, its purity directly affects the performance and quality of chips.
