摘　　要：采用"擦洗—脱泥—磁选—浮选—分级"的主要工艺流程,对江西修水高纯石英矿进行提纯试验。对+0.104mm产物进行"酸浸—高温爆裂"试验,可得到SiO2质量分数≥99.98%,TFe2O3为4.46μg/g的高纯石英;对-0.104mm产物进行"擦洗"试验,可获得D90=12.05μm,SiO2质量分数为99.90%的超细硅微粉。The main technological process of ＇scouring-desliming-magnetic separation-flotationclassification＇was adopted in the program of studying on concentration test of quartz from Jiangxi Xiushui. The test by process of ＇acid leaching - high temperature bursting＇ was carried out on the oversize product of 0. 104 mm. The final product could be obtained with the content of SiO2 above 99.98%and Fe2O3 being 4.46μg/g. With the help of scouring , the concentrate of screen product contains SiO2 99. 90% and the particle size of 90% product is no more than 12.05μm.
