摘要: 通过光学显微镜、电子探针、X射线衍射、化学分析、MLA等分析手段,对高磷鲕状赤铁矿石的化学组成、矿物组成、矿物嵌布及鲕粒特征进行了详细研究.结果表明:矿石中的铁主要赋存于赤铁矿和褐铁矿中,主要脉石矿物为石英、鲕绿泥石和胶磷矿.矿石矿物组成复杂,赤铁矿通常与石英、鲕绿泥石、胶磷矿和黏土矿物层层环状包裹形成鲕粒.鲕粒可分为富铁鲕粒和贫铁鲕粒,其粒度主要为01~05mm.此研究结果为该铁矿资源的合理开发利用提供了依据.

关键词: 鲕状赤铁矿, 矿物学, 矿物组成, 嵌布特征, 鲕粒特征

Abstract: The chemical composition, mineral composition, dissemination characteristics and ooidal characterization of the oolitic hematite ore were detailedly investigated through optical microscope, electron probe, XRD, MLA automatic detection and chemical analysis. The results showed that iron mainly occurs in the form of hematite and limonite,and the primary gangue minerals are quartz, chamosite and collophanite. Mineral composition of the ore is complex, and hematite is usually wrapped with annular and layer upon layer by quartz, chamosite, collophanite and clay minerals to form ooids. Ooids in the ore can be divided into ironrich ooid and ironpoor ooid, which are mostly distributed in the size range of 01~05mm. The results may provide the basis for the rational exploitation for the iron ore resource.

Key words: oolitic hematite, mineralogy, mineral composition, dissemination characteristics, ooidal characterization
