In order to find a new way to utilize the high phosphorus oolitic hematite ore as raw material for steelmaking, the reduction and carburization of high phosphorus oolitic hematite by the gas of CH4-H2were studied. High phosphorus oolitic hematite, reduction and carburization products were investigated by the means of XRD and scanning electron microscope. The SEM-EDS and XRD analysis show that the main compositions of this ore are hematite and quartz, main microstructure is oolitic cluster with the zonal distribution of hematite and apatite, and iron carbide can be prepared from high phosphorus oolitic hematite.

Through using jiuquan bituminous coal, yangquan anthracite, coking coal and charcoal as fuel,under 900 °C simulating the preheat layer of sinter process,research the influence of fuel types and content on gasification dephosphorization.Results show that due to the different volatile matter of coal, the influence on gasification dephosphorization is different, the influence of the highest volatile bituminous coal to the dephosphorization effect is best when carbon content takes 4%.
