摘要: 通过光学显微镜、化学分析、X射线衍射、扫描电镜等分析手段,对硼铁矿石的化学组成、矿物组成、元素赋存状态、各矿物间的嵌布关系及粒度分布进行了详细研究.结果显示:硼铁矿石矿物组成复杂,种类繁多,主要含硼矿物为硼镁石和硼铁矿,其中硼镁石含硼量占硼总量的89.01%,主要含铁矿物为磁铁矿,85.60%的铁赋存于磁铁矿中,蛇纹石是主要脉石矿物;硼镁石、磁铁矿、硼铁矿和蛇纹石嵌布关系复杂,嵌布粒度粗细不均,硼镁石、磁铁矿、蛇纹石嵌布粒度相对较粗,硼铁矿嵌布粒度相对较细.

关键词: 硼铁矿, 矿物学, 矿物组成, 嵌布特征, 粒度分布

Abstract: The chemical composition, phase composition, occurrence state of element, dissemination relationship and size distribution of the paigeite ore were analyzed by optical microscope, chemical analysis, XRD and SEM analysis. The results show that mineral composition of the paigeite ore is very complex. Main boron minerals are szaibelyite and paigeite, boron content in szaibelyite accounting for 89.01% of total boron content. Main iron mineral is magnetite, iron content in magnetite being 85.60% of the total iron content. Serpentine is the main gangue mineral. The dissemination relationship among szaibelyite, magnetite and serpentine is complex, and dissemination particle size distribution of different minerals is uneven. Dissemination particle sizes of szaibelyite, magnetite and serpentine are coarser, while that of paigeite is fine.

Key words: paigeite, mineralogy, mineral composition, dissemination characteristic, particle size distribution
