| 摘 要： | 对云南某钛铁矿进行了工艺矿物学研究。结果表明: 矿石中钛品位为5.62%，主要有用金属矿物为钛铁矿和钒钛磁铁矿，分别占总钛的61.39%和11.03%。脉石矿物主要是斜长石和钛辉石，脉石矿物中主要成分为SiO2和Al2O3，其含量分别为42.35%和12.53%。矿样中粗粒钛铁矿多与钒钛磁铁矿和榍石及硅酸盐紧密共生，其集合体的粒度主要集中在 0.02～0.30 mm。赋存于榍石与硅酸盐矿物中的钛多达27.58%。探索性实验结果表明:弱磁-强磁选可以有效地回收矿石中的强磁性矿物，并抛出大量的脉石矿物，实现钛铁矿的富集。因此，该矿石属于低品位难选钛铁矿，实现钛铁矿物的有效回收对该资源的开发利用具有重要的实践意义。

| Abstract: | The process mineralogy of an ilmenite in Yunnan Province was studied. The results showed that the grade of titanium in the ore sample was 5.62%. The main metal minerals in the ore were ilmenite and vanadium ilmenite, which occupied for 61.39% and 11.03% of the total titanium, respectively. The gangue minerals were plagioclase and titanaugite. The contents of SiO2 and Al2O3 were 42.35% and 12.53%, respectively. Most of the coarse ilmenite minerals in the samples were closely associated with vanadium ilmenite, sphene and silicate. Meanwhile, the particle size of the aggregation was mainly concentrated in 0.02～0.30 mm, whereas, 27.58% of titanium occurred in sphene and silicate minerals. Exploratory experimental results of low intensity-high intensity magnetic separation indicated that the strong magnetic minerals could be recovered and plenty of gangue minerals could be removed effectively, resulting in the concentration of ilmenite minerals. Thus, the ore belonged to a low grade refractory ilmenite and it will be significant importance to recover the ilmenite effectively for the exploitation and utilization of this resource. |
