Fundamental Research in Comprehensive Utilization of Bayan Obo Ore by Direct Reduction

Abstract:

With the problems of hard processing, low efficiency and heavy pollution in Bayan Obo ore, A new combination flowsheet of coal-based direct reduction - benificiation was proposed to deal with the ore. By adjusting the parameters of temperature, time and ratio of carbon, the procedure of direct reduction is optimized and the iron is enrichment effectively. Experimental results show that the with the conditions of reduction temperature is 1225°C, reduction time is 30 mins and ratio of carbon is 2, the grade, metallization rate and recovery of the iron powder are 93.33%, 94.18% and 88.93% respectively. The iron powder by this process can be used as the raw material of converter steel making.
