摘要
The process of coal-based direct reduction followed by magnetic separation was employed to produce direct reduction iron powder (DRIP) from a refractory low-grade iron ore. The desulfuration behavior of the composite briquettes during this process was studied. Experimental results showed that this process presents advanced sulfur removal ability. The sulfur contained in the composite briquette was almost reserved in the form of troilite at the reduction stage; however, after grinding and magnetic separation the sulfur was removed efficiently into the tailing, and the DRIP with low content of sulfur was obtained.
