Abstract

Abstract

The experimental study on mineral processing of kaolinite accompanied by quartz in Guangdong was carried out in order to obtain quartz sand products meeting the requirements. The tailings were obtained after the kaolin raw ore was mashed and graded to separate the −0.045 mm particle size kaolin product. The +0.1 mm grain size material accounting for 99.13% of the tailings can be used as quartz raw material for glass. Two kinds of process comparison tests of "color sorting−grinding−magnetic separation" and "grinding−magnetic separation" were conducted on the +0.6 mm particle size. Results indicated that, color sorting had a relatively small impact on the final separation index, so grinding−magnetic separation was sufficient; Quartz concentrate with Fe₂O₃ content less than 120 μg/g and quartz concentrate with SiO₂ content of 99.04%, Fe₂O₃ content of 104.46 μg/g were obtained by magnetic separation from + 0.6 mm particle size and grinding−magnetic separation from −0.60 +0.10 mm particle size, respectively, which can meet the standard of quartz sand for photovoltaic glass. This study is helpful to the comprehensive utilization of kaolinite associated quartz sand, and can enhance the value of associated quartz sand.
