Abstract: The iron grade of Shuichang iron deposit in Eastern Hebei is 32.27%.The main iron mineral is magnetite，the distribution rate of iron in magnetite is 91.72%，followed by ferric metasilicate and iron carbonate，with distribution rate of 5.30% and 2.49%，respectively.Gangue minerals are mainly quartz，pyroxene and hornblende.The analysis on the technological mineralogy of the iron ore was carried out to provide technique basis for the development of the ore.The ore structures are mainly granoblastic structure，followed by sideronitic and crushed structure.While the ore textures are mainly streaky and banded texture，and minority is gneissic and massive texture.Various types of magnetite disseminated in the ore，most of which in hypidiomorphic-allotriomorphic structure，granular embedded in gangue minerals such as quartz，pyroxene，hornblende，etc..Magnetite are unevenly disseminated，8.42% distributed in +0.64 mm fraction；38.90% distributed in -0.08 mm fraction，among which 22.14% distributed in 0.04 mm fraction.So stage grinding stage separation process is suitable for sorting of the iron ore.
