Abstract: In order to provide basis for separation process of Anshan Hu Jiamiao poor hematitel， the process mineralogy on the ores are studied，which adopt X- ray diffraction， microscopy， QuantLab-CD image analyzer Analysis and detection methods. The results show that only 25.88% grade iron ore，iron ore mainly hematite， the illusion of hematite，magnetite form， magnetite and hematite are closely associated，disseminated coarse granularity ，some micro-fine particles of martite are contained by quartz or other gangue. gangue minerals disseminated coarse-grained in the ore， the mainly gangue are quartz， tremolite， actinolite， chlorite and a small amount of clay minerals，has little effect on the dressing，which is easy to choose iron ore.
