摘要 针对脉石英矿中含有大量云母及长石等伴生矿的特点,通过调整溶液浓度及温度等手段,强化矿物的酸浸效果.根据石英与杂质矿物在酸浸过程中的差异,探索消除石英中杂质矿物的方法.研究表明石英原料粉在温度为120℃、HF酸与水的比为0.4~0.5的溶液中酸浸适当时间后,其纯度可达到中高档石英玻璃的技术要求. Owing to the impurity minerals,such as mica and feldspar,quartz veins are not the best choice of the raw mineral of quartz glass. In this study,we strengthened the effect of leaching process at the temperature above 100 ℃ ,proper content of HF acid and leaching time,which can further eliminate the impurity element to make high purity quartz power.
