AI Technical Summary
Existing technologies are insufficient to effectively remove lattice titanium and titanium inclusions from high-purity quartzite, resulting in limited improvement in product purity.
The process employs a coupled process of calcination and water quenching, flotation for impurity removal, acid leaching for purification, chlorination roasting, and secondary acid leaching. Calcination creates microcracks, flotation and acid leaching are used to remove titanium impurities, and chlorination roasting and secondary acid leaching are combined for further purification.
It significantly improves the purity of quartz sand to over 99.995%, meeting the requirements of 4N5 grade high-purity quartz, and effectively removes lattice titanium and inclusion titanium.
