Abstract: A certain iron ore in Shahe County，Hebei province，is rich in iron and contains valuable elements such as sulfur and cobalt. In order to study the process mineralogical characteristics of the ore and formulate a reasonable beneficiation scheme for achieving the comprehensive utilization， the research about material composition，ore structure，embedding characteristic of the major minerals，degree of dissociation of the value minerals were carried out by chemical analysis， XRD， microscope and MLA. The results showed that the contents of Fe，CO and S are 39.98%，0.017% and 1.89%， respectively. Fe is mainly in the form of magnetite，Co and S are mainly in the form of pyrite. The main gangues minerals are carbonate minerals like calcite and dolomite. The ore is mainly massive structure and granular structure. Magnetite and pyrite are mainly medium and fine particles， which are closely related to each other， so better monomer dissociation degree needs to be obtained by fine grinding.According to the results of process mineralogy，the mineral process of “discarding by dry magnetic separation， grinding，iron selection by low intensity magnetic separation，flotation for cobalt and sulfur” is recommended for the ores.
