    2019-3-1 · 1. Introduction. Phosphorus is a deleterious component in the iron-making industry, as it results in “cold shortness” of steel, and iron ores receive a price penalty if they exceed 0.07–0.08 wt% P. (Cheng et al., 1999).At current mining rates, it is predicted that the premium-grade iron ore with low phosphorus will deplete within the next 30 years (Han et al., 2015).
