摘要
对四川某地石英砂矿进行了选矿和化学提纯试验研究,最终通过采用磨矿、强磁、浮选、酸浸等工艺,脱除了石英中的杂质元素,获得的石英精矿SiO2含量≥99.95%、Fe2O3≤0.001%、Al2O3≤0.01%,达到了高纯石英砂的标准。
Ore dressing and chemical purification study were conducted on quartz sand in Sichuan to remove the impurities .By the process of grinding , high-intensity magnetic separation , flotation and acid leaching , a high purity quartz product was obtained which contains higher than 99 .95%SiO2,less than 0.001%Fe2O3 and less than 0.01%Al2O3, respectively.
