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
