摘要

摘要: 钛矿石的主要矿物有金红石（TiO2），其次钛铁矿(FeO·TiO2)、榍石(CaO·TiO2·SiO2)和钛磁铁矿（FeTiO3·nFe2O3）。样品经碱熔融，过氧化氢比色测定总钛；利用电感耦合等离子体质谱法测定，氟化氢铵和盐酸溶解钛铁矿、钛磁铁矿、榍石和硅酸盐中的钛；湿法磁选、盐酸溶解钛磁铁矿中的钛；磁选后的残渣经800℃灼烧，氟化氢铵和盐酸溶解榍石和硅酸盐中的钛。方法对12个钛矿石样品进行了4种钛矿物物相分析，结果与实际地质成矿组分符合。

Abstract: The main titanium minerals include rutile (TiO2), ilmenite (FeO·TiO2), sphene (CaO·TiO2·SiO2) and titanomagnetite (FeTiO3·nFe2O3). The methods used for rapid phase analysis of titanium minerals were introduced in this paper. The total titanium in the samples was determined by hydrogen peroxide colorimetry after sample decomposition with alkali fusion. And titanium in the mineral phases was determined by inductively coupled plasmamass spectrometry (ICP-MS) coupled with 3 sample decomposition methods: (1) NH4HF2-HCl digestion for ilmenite, sphene, titanomagnetite and silicate phases, (2) wet magnetic separationHCl digestion for ilmenite phases, (3) NH4HF2-HCl digestion of magnetic residue after roasting at 800℃ for sphene and silicate phases. The method has been applied to the analysis of four titanium mineral phases in 12 titanium ores with satisfactory results.
