内蒙古某白伟晶岩纯化制备高纯石英砂

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

    • 摘要: 这是一篇矿物加工工程领域的文章。针对内蒙古某白伟晶岩样品进行工艺矿物学研究,采用“焙烧水淬-热压混合酸浸”实验工艺流程对内蒙古某地白伟晶岩进行选矿实验研究。通过条件实验研究得到较佳工艺条件,高纯石英砂中SiO2含量由99.917%提高到99.994%,杂质元素总含量从419.9 g/t下降到54.79 g/t,总去除率达86.95%;主要杂质元素Al含量从250.9 g/t下降到26.09 g/t,Al元素去除率达到了89.60%,取得了较好的纯化效果。

       

      Abstract: This is an essay in the field 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 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.
