Preparation of High-purity Quartz Sand by Purifying a White Pegmatite in Inner Mongolia

Blog Article

This is an essay in the field of mineral processing engineering.Based on the chicago cubs earrings process mineralogy, a mixed process containing roasting-water quenching-hot pressure leaching was applied to purify a white pegmatite ore from Inner Mongolia.The optimum condition was obtained via various tests.The content of SiO2 in the final product was increased from 99.917% to 99.

994%, while the total impurity content soiebiologique.com was decreased from 419.9 to 54.79 g/t, with a total removal of 86.95%.The main impurity element of Al was decreased from 250.

9 g/t to 26.09 g/t, with a removal of 89.60%.Therefore, this study provides a good purification approach for high-purity quart preparation.
