Purification of Quartz from East Qinling Granitic Pegmatite for the Preparation of High-Purity Quartz Sand
High-purity quartz is an important raw material for strategic emerging industries, including photovoltaics and semiconductors. To improve the deep removal of impurities from granitic-pegmatite quartz and clarify the effects of calcination–water quenching, a quartz concentrate from the East Qinling Mountains was selecte...
