Process mineralogy characteristics of Anshan Hu jiamiao Liaoning lean Hematite

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.
