| 摘 要： | 以广西平果县太平铝土矿区外围的矿石为研究对象,采用化学分析、X射线粉晶衍射、光学显微鉴定、X射线能谱分析等方法对矿石的化学组成、矿物组成、矿物嵌布特征等进行了系统研究。结果表明,太平矿区外围铝土矿属于高铁的一水硬铝石型铝土矿,其中Al_2O_3含量为53. 06%,A/S值为10. 74,适用于拜耳法回收;共伴生组分中Fe_2O_3、Ti O_2、Ga、Nb达到综合回收利用指标。矿石选冶回收的目标元素Al主要以一水硬铝石、三水铝石的形式存在,平衡配分占比分别为85. 9%、6. 73%。矿石复杂的结构构造、矿物嵌布粒度、矿石中Fe、Si等元素不均匀分布等因素对Al的选冶回收有一定的影响。

| Abstract: | Taking the ore in the periphery of the Taiping bauxite mining area in Pingguo County of Guangxi as the research object, the authors systematically studied the chemical composition, mineral composition and mineral distribution characteristics of the ore by means of chemical analysis, X-ray powder diffraction, optical microscopic identification and X-ray energy spectrum analysis. The results show that the bauxite in the periphery of the Taiping mining area belongs to diaspore type bauxite with high iron content, with Al2O3 53.06% and A/S ratio 10.74, which is suitable for Bayer process recovery; Fe2O3, TiO2, Ga and Nb in the associated components have achieved comprehensive recycling indices. The target element Al for ore smelting and recovery is mainly in the form of diaspore and gibbsite, whose phase proportions are 85.9% and 6.73%, respectively. The complex structure of the ore, the size of the mineral dissemination, the uneven distribution of Fe, Si and other elements in the ore have certain effects on the selection and recovery of Al element. |
