摘要: 通过化学分析、X 射线衍射、光学显微镜、电子探针、MLA 等分析手段,对辽宁本溪思山岭铁矿石的化学组成、矿物组成、矿物产出形式、嵌布特征及连生关系等进行了详细研究.结果表明:矿石中的铁主要赋存于磁铁矿和赤铁矿中,主要的脉石矿物为石英和含铁白云石,磁铁矿被赤铁矿交代残余、紧密连生,自形晶粒状铁矿物集合体不规则赋存于石英或白云石矿物中,磁铁矿嵌布粒度微细.此研究结果为该铁矿综合利用提供了重要依据.

关键词: 思山岭铁矿, 矿物学特征, 矿物组成, 嵌布特征, 粒度分布

Abstract: The chemical composition, mineral composition, dissemination characteristics and grain size composition of Sishanling iron ore in Beixi City, Liaoning were investigated through chemical analysis, XRD, optical microscope, electron microprobe and MLA. The results showed that the iron minerals mainly occur in the form of magnetite and hematite, and the primary gangue minerals are quartz and iron-containing dolomite. Magnetite is replaced by hematite with closely complex and intergrowth relation, and the euhedral grain like iron minerals aggregates are irregularly distributed in quartz or dolomite. The disseminated grain size of magnetite is fine. The results may provide a foundation for the rational development and utilization the iron ore resource.

Key words: Sishanling iron ore, mineralogical feature, mineral composition, dissemination characteristics, size distribution
