| 中文摘要: |
| 本文以湖北宜都鹰子咀石英砂岩矿为原料采用磨矿—磁选、磨矿—磁选—浮选、磨矿—磁选—浮选—酸洗、磨矿—磁选—混酸酸浸等工艺进行除铁选矿对比分析。磨矿—磁选工艺后， Fe2O3含量由 1330×10-6大幅降低至 240. 59×10-6；磨矿—磁选—浮选后， Fe2O3含量由 240. 59×10-6降低至 198. 71×10-6；磨矿—磁选—浮选—酸洗工艺后， Fe2O3含量由 198. 71×10-6降低至 122. 71×10-6；最终确定磨矿—磁选—混酸酸浸工艺可以大幅降低杂质元素铁含量，达到光伏超白砂超低铁质量要求(Fe2O3≤100×10-6)。 |
| 英文摘要: |
| Taking Yingzizui quartz sandstone ore from Yidu，Hubei Province as raw material，a comparative analysis of iron removal was carried out by grinding -magnetic separation，grinding -magnetic separation -flota. tion，grinding -magnetic separation -flotation -pickling，grinding -magnetic separation -mixed acid pickling and other processes. After grinding and magnetic separation process，Fe2O3 content decreased from 1330×10-6 to 240. 59×10-6. After grinding，magnetic separation-flotation，Fe2O3 content decreased from 240. 59×10-6 to 198. 71× 10-6. The Fe2O3 content decreased from 198. 71×10-6 to 122. 71×10-6 after grinding，magnetic separation-flotation and pickling process. Finally，it is determined that the grinding，magnetic separation-mixed acid leaching process can greatly reduce the content of impurity elements iron and meet the ultra-low iron quality requirements of photovoltaic ultra-white sand(Fe2O3≤100×10-6). |
