Abstract :
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°C; 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.
