A Review on Removal of Iron Impurities from Quartz Mineral
The effect of crystal structure transformation on iron impurity removal in quartz sand was studied. Research showed that the transformation of crystal structure can effectively improve the efficiency of removing iron impurities. After roasting at 900 °C for 4 h, it was found that β-quartz content was as high as 94.7%.Le sable de quartz est utilisé comme charge dans la fabrication de caoutchouc, de peinture et de mastic. Les grains tamisés et lavés, soigneusement calibrés, sont utilisés comme média filtrant et granulés de couverture.
