【摘要】：采用阴极发光显微镜、ICP-OES和SEM-EDS等分析测试手段研究了花脖湾石英岩的矿石性质,以解离并去除白云母为提纯目标进行了浮选和酸浸条件优化试验。结果表明:花脖湾石英岩质地纯净,w(SiO_2)高达99.00%,白云母是主要脉石矿物,优化试验确定的浮选条件为:矿浆pH值2.5,DDA用量140g/t;酸浸条件为:混合酸质量分数30%,温度55℃,时间120min。在超声波辅助作用下提纯获得的细粒级(0.110~0.074mm)石英砂9种杂质元素总含量降低至66.65×10-6,w(SiO_2)达到99.99%。花脖湾石英岩矿经试验证实为一种石英岩型高纯石英原料,作为高纯石英资源应用前景广阔。
[Abstract]:The ore properties of Huabaowan quartzite were studied by means of catholuminescence microscope, ICP-OES and SEM-EDS. The flotation and acid leaching conditions were optimized with the aim of separating and removing Muscovite. The results show that the pure, w (SiO_2 of quartz in Huayaowan is as high as 99.00. Muscovite is the main gangue mineral. The optimum flotation conditions are as follows: the pH value of pulp is 2.5g / t, and the acid leaching conditions are as follows: the mass fraction of mixed acid is 30, the temperature is 55 鈩，
