摘 要:采用3种常用硅砂选矿工艺流程对石英砂进行试验研究,并对3种工艺的机理进行了分析。结果表明,氢氟酸法较无氟浮选法和碱法浮选法分选效果好,采用氢氟酸法获得了石英产率67.85%、Al2O3含量1.02%、Fe2O3含量0.068%的技术指标,长石和石英得到了较好的分离。Three common separation processes for the quartz sand are studied in the paper and their mechanisms are discussed. The results show that the hydrofluoric acid method can achieve much better performance than non-fluoride with acid method and alkali method, adopted the process of the hydrofluoric acid method, got the quartz concentrate with a yield of 67.85%, Al2O3 content of 1.02%, Fe2O3 content of 0.068%, quartz and feldspar can be effectively separated.
