摘要: 江苏某蓝晶石矿石品位低、杂质矿物种类较多、蓝晶石与杂质矿物相嵌关系复杂,属难选矿石。为了给该蓝晶石资源的开发利用提供依据,对其进行了选矿试验。结果表明:采用磨矿—高梯度磁选除铁钛—按45 μm分级—细粒级脱泥—脱泥沉砂和粗粒级分别酸性浮选工艺流程,可以获得Al2O3品位为55.69%、Al2O3回收率为 69.23%的蓝晶石精矿1和Al2O3品位为50.17%、Al2O3回收率为 15.16%的蓝晶石精矿2;精矿1达到国家行业标准中LJ-55牌号蓝晶石精矿的质量要求,精矿2可用作陶瓷原料。

Abstract: Due to low grade,various impurities and complex embedment relationship between kyanite and impurities,a certain kyanite ore in Jiangsu belongs to a refractory ore. In order to provide a basis for the development and utilization of the kyanite resources,the related beneficiation tests were carried out. The results show that: through the process of grinding-iron and titanium removal by high gradient magnetic separation-grading at 45 μm- desliming and settlement for fine particles-acidic flotation for coarse particles,kyanite concentrate 1 with Al2O3 grade of 55.69% and Al2O3 recovery of 69.23% and kyanite concentrate 2 with Al2O3 grade of 50.17% and Al2O3 recovery of 15.16% were gained respectively. Concentrate 1 meets the quality requirements for national industry standards of LJ-55 kyanite concentrate,and concentrate 2 can be used as ceramic raw materials.
