我国氯化法钛白生产所需高品质钛原料长期依赖进口优质冶炼钛渣与富钛料，制约了产业技术升级与自主保障能力。为提高攀西地区典型岩矿型钛资源的综合利用价值，以白马矿区橄辉岩型钛精矿为研究对象，针对其TiO₂品位偏低(47.07%)、钙镁硅等杂质含量较高(SiO_2+CaO 2.67%,MgO 5.16%)的特点，系统开展了重选、磁选、浮选和电选四种物理选矿工艺的提质对比试验。结果表明，重选与电选在获得高品质钛精矿方面具有明显优势：重选可获得TiO₂品位50.03%、SiO_2+CaO含量0.73%、MgO含量3.33%、TiO₂回收率62.50%的精矿；电选可获得TiO₂品位49.97%、SiO_2+CaO含量1.26%、MgO含量3.77%、TiO₂回收率64.41%的精矿。而磁选与浮选工艺难以稳定获得TiO₂品位≥50.0%的产品。杂质脱除行为分析表明，随着精矿TiO₂品位升高，SiO₂、CaO、MgO、Al_2O₃含量总体呈下降趋势，其中重选对SiO₂和MgO的脱除效果尤为显著。综合技术指标与工艺适用性，重选被视为该类型钛精矿提质较适宜的工艺，可为制备沸腾氯化用高品质钛原料提供技术支撑。

The production of high-quality titanium raw materials for China's chloride-process titanium dioxide industry has long relied on imported high-grade smelting titanium slag and titanium-rich materials, which restricts industrial technological upgrading and self-sufficiency. To enhance the comprehensive utilization value of typical rock-type titanium resources in the Panxi region, this study takes olivine pyroxenite-type titanium concentrate from the Baima mining area as the research object. Given its characteristics of low TiO₂ grade(47.07%) and high impurity content such as calcium, magnesium, and silicon(SiO_2+CaO 2.67%, MgO 5.16%), systematic comparative experiments on quality improvement were carried out using four physical beneficiation methods: gravity separation, magnetic separation, flotation, and electrostatic separation. The results show that gravity separation and electrostatic separation have significant advantages in obtaining high-quality titanium concentrate. Gravity separation produced a concentrate with a TiO₂ grade of 50.03%, SiO_2+CaO content of 0.73%, MgO content of 3.33%, and TiO₂ recovery of 62.50%. Electrostatic separation yielded a concentrate with a TiO₂ grade of 49.97%, SiO_2+CaO content of 1.26%, MgO content of 3.77%, and TiO₂ recovery of 64.41%. In contrast, magnetic separation and flotation struggled to consistently achieve a TiO₂ grade≥50.0%. Analysis of impurity removal behavior indicates that as the TiO₂ grade of the concentrate increases, the contents of SiO₂, CaO, MgO, and Al_2O₃ generally decrease, with gravity separation showing particularly significant effectiveness in removing SiO₂ and MgO. Considering both technical indicators and process applicability, gravity separation is regarded as the more suitable method for improving the quality of this type of titanium concentrate, providing technical support for the preparation of high-quality titanium raw materials suitable for fluidized chlorination.
