| 摘 要： | 针对沐川黄丹石英砂岩选矿提纯工艺,采用多种岩矿现代测试分析方法,对该矿工艺矿物学进行研究,结果表明:该矿为一种硅泥质中粒含长石石英砂岩,石英碎屑粒径范围0.2mm～0.5mm;原矿以石英为主,结晶度高,含量90%左右,同时含少量或微量其它杂质矿物,它们是蒙脱石、伊利石、高岭石、微斜长石和方解石,以及黄铁矿、水铁矾、金红石、板钛矿等;对矿石质量影响较大是粘土矿物和黄铁矿,它们以粒间填隙物无序散布于石英颗粒之间;原矿w(SiO2)/%为94.02,w(Al2O3)3.88%,w(K2O)1.28%,w(CaO)0.18%等有害成分赋存于蒙脱石、伊利石、高岭石、微斜长石和方解石等矿物中;w(Fe2O3)0.09%主要赋存于黄铁矿中,也有部分来源于水铁矾和粘土矿物。
