Reaction Behavior of Phosphorus in Coal-Based DOAJ

01.04.2016 · Coal-based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus-containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction

China makes breakthrough in iron ore dephosphorization

The dephosphorization of high-phosphorous iron ore had up to now been a long-standing unresolved technical problem in China. During the iron and steel making processes, phosphorous can seriously affect the quality of pig iron and steel, causing brittleness in particular. As a result, the mining industry requires that the content of phosphorous in hematite should be lower than 0.2 percent.
