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

Blog Article

This is an essay in the field rubbermaid 8 gallon trash can of mineral processing engineering.Based on the 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 was decreased from 419.9 to 54.79 g/t, with a total removal of 86.

95%.The main impurity element of Al click here 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.
