摘要: 采用传统工艺矿物学研究方法,结合光学显微镜、X射线衍射、化学分析等分析手段,对朝阳地区钒钛磁铁矿石的化学组成、元素赋存状态、矿物组成、矿物间的嵌布关系及粒度分布进行了详细研究.结果显示:该铁矿石中铁矿物主要为磁铁矿、钛磁铁矿和钒磁铁矿,长石是最主要的脉石矿物.矿石中主要矿物嵌布关系复杂,磁铁矿与钛磁铁矿颗粒结合紧密,大多结合成连生体,不利于铁矿物与钛矿物之间单体解离;主要矿物嵌布粒度粗细不均,磁铁矿嵌布粒度相对较粗,钛磁铁矿和钒磁铁矿嵌布粒度相对较细.该研究为该地区钒钛磁铁矿资源的合理开发利用提供了依据.

Abstract: The chemical composition, occurrence state of elements, mineral composition, dissemination relationship and size distribution of the vanadium titanium magnetite ore in Chaoyang were analyzed through traditional process mineralogy method and optical microscope, XRD, chemical analysis, etc. The results show that mineral composition of this ore is very complex. Primary recoverable minerals are magnetite, titanomagnetite and coulsonite, and feldspar is the main gangue mineral. The dissemination relationship among main minerals is complex, magnetite is closely linked to titanomagnetite with great difficulty to be separated. Dissemination particle size of magnetite is coarse, while that of titanomagnetite and coulsonite is fine. The results may provide the basis for the rational exploitation of the vanadium titanium magnetite resource.

Key words: vanadium titanium magnetite, mineralogy, mineral composition, dissemination characteristics, occurrence state of elements, size distribution
