Study on the Purification Conditions of Silica Dust

摘要：

This article focused on the purification conditions of silica dust JiaYuGuan of GanSu. The best processing conditions turned out to be as following: calcinations temperature, 700℃; calcinations time, 120min; rate(m/m) of HCl solution(10%, by mass) and silica dust, 3.5:1; acid-dipping time, 5h. The silica dust that the percent of SiO2 was above 95%(by mass) were obtained.
