| 摘 要： | 通过以自动化电子探针和扫描电镜为基础的矿物扫描和定量分析,研究了云南某地风化型钛铁矿的工艺矿物学。结果表明,矿石中TiO2(5.68%)为有回收价值的金属,钛铁矿和钛磁铁矿为含钛主要矿物,含钛占总量的80.7%,高岭石、蒙脱石和辉石为主要的脉石矿物,选择-0.45 mm作为最佳的磨矿细度以确保钛矿物的单体解离。该研究对于选别风化型钛铁矿具有一定的指导意义。

| Abstract: | A detailed mineralogical characterization of a weathered titanium ore from Yunnan was studied by automated electron microprobe and SEM based mineral mapping and quantitative analy -sis.The results show that the ore contains 5.68%TiO2 , which is the desirable to recover .The main titanium mineral are ilmenite and titanomagnetite , which account for 80 .7% of the total titanium . Kaolinite, montmorillonite and pyroxene are the main gangue mianerals .The optimal grinding fine-ness is 0.045 mm, to make sure that most of the titanium minerals can be liberated from other min-erals.The research could be a reference to beneficiation of weathered ilmenite ores . |
