| 摘 要： | 以攀枝花钒钛磁铁矿电炉渣为研究对象,通过化学分析、X射线衍射及电子探针-能谱等手段对电炉渣的化学组成、矿物组成、矿物嵌布特征、元素分布情况进行了较为系统的研究,结果表明:电炉渣中有94.74%的钛赋存于黑钛石中,镁和铝主要以镁铝尖晶石形式存在,钙和硅主要存在透辉石中,而铁元素在各矿物中分布较为分散。有用矿物黑钛石主要与透辉石呈浸染关系,部分与镁铝尖晶石呈嵌布关系,同时有部分镁和铝以类质同像形式进入到黑钛石中,导致黑钛石中TiO_2含量仅82.04%。研究结果可为钒钛磁铁矿电炉渣的综合利用提供科学依据。

| Abstract: | Taking vanadium-titanium magnetite electric furnace slag as the research object, the authors systematically studied chemical composition, mineral composition, mineral and element distribution characteristics of the slag by means of chemical analysis,X-ray diffraction analysis and electron microprobe analysis. The results show that 94.74% Ti exists in anosovite, Mg and Al mainly occur in the form of magnesia alumina spinel, calcium and silicon are mainly in the form of diopside, while iron is dispersed in various minerals. The valuable mineral is anosovite, which is mainly disseminated with diopside, and partly distributed in spinel. Besides, some of Mg and Al occur in anosovite in the form of isomorphous admixture; as a result, the content of TiO2 in anosovite is only 82.04%. The result can provide scientific basis for the comprehensive utilization of vanadium-titanium magnetite electric furnace slag. |
