摘要: 钛渣是生产钛白粉的核心原料，但其含有的Ca、Mg等杂质元素严重影响钛白粉产品纯度。本文以钛渣为研究对象，采用正交试验法，结合成分解析、氧化特性研究等手段，系统探究氧化法提纯钛渣的可行性。通过X射线衍射(XRD)等精密检测技术，对比分析氧化处理前后钛渣中钛组分的变化，并进一步研究氧化改性钛渣含钛物相的物理冶金分选方法。结果显示：氧化处理对钛渣化学成分影响微弱，但显著改变其物相结构；钛元素主要富集于金红石相，Ca、Mg等杂质则集中在硅酸盐与板钛矿中，该物相转变为物理冶金除杂提供了理论支撑。磁选–浮选联合工艺研究表明：直接浮选除杂后精矿TiO2品位达75.25%；磁选可有效脱除Fe氧化物等磁性杂质，其尾矿再经浮选能去除Ca、Mg等杂质，最终浮选精矿TiO2品位提升至79.33%。
Abstract: Titanium slag is the core raw material for titanium dioxide production, but its inherent impurity elements such as Ca and Mg severely affect the purity of titanium dioxide products. Taking titanium slag as the research object, this paper systematically explores the feasibility of purifying titanium slag by oxidation method using orthogonal test, combined with component analysis, oxidation characteristics research and other means. Through precise detection technologies such as X-ray diffraction (XRD), the changes of titanium components in titanium slag before and after oxidation treatment are compared and analyzed, and the physical metallurgical separation method for titanium-bearing phases in oxidation-modified titanium slag is further studied. The results show that oxidation treatment has a negligible effect on the chemical composition of titanium slag but significantly changes its phase structure; titanium is mainly enriched in rutile phase, while impurities such as Ca and Mg are concentrated in silicates and anatase, and this phase transformation provides theoretical support for physical metallurgical impurity removal. The research on the magnetic separation-flotation combined process indicates that the TiO2 grade of concentrate reaches 75.25% after direct flotation for impurity removal; magnetic separation can effectively remove magnetic impurities such as Fe oxides, and the tailings after magnetic separation can further remove impurities such as Ca and Mg through flotation, with the final TiO2 grade of flotation concentrate increased to 79.33%.
