Abstract
In this study, we have investigated the purification characteristics of quartz which size was 0.1mm to 0.3 mm by using physical separation techniques. The A and B samples which contained 95,864 mg/kg and 4,568 mg/kg of impurities were reduced upto 126 mg/kg and 174 mg/kg of impurities, respectively. So, removal ratios of the total impurities were about 97.85 wt.% and 96.19 wt.%, individually. At that time, the yields of the purified quartz (over 99.98 wt.% $SiO_2$) were 79.05 wt.% and 75.43 wt.% by using purification process including magnetic separation, gravity separation and scrubbing process. The most benefit in purification process of both different raw materials for iron element can be achieved by magnetic separation. Also, gravity separation is extremely successful for reducing aluminium element.
