Characterisation of phosphorus and other impurities in

11/1/2019· Current specifications for phosphorus in iron ore require ores averaging less than 0.07–0.08 wt-% P (Cheng et al., 1999, Thorne et al., 2008), with penalties for every 0.001 wt-% increase in P above the acceptable limit (Cheng et al., 1999).

Steelmaking Wikipedia

Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained impurities

Characterization studies on Agbaja iron ore: a high

2/2/2019· Iron ores can be classified with respect to their phosphorus content as low-phosphorus ore (< 0.07% P), medium-phosphorus ore (0.07–0.10% P), or high-phosphorus ore (> 0.10% P) [ 5 ]. High-phosphorus iron ores abound worldwide and constitute the bulk of “low grade” iron ores.

Processes for phosphorus removal from iron ore a review

The way in which phosphorus is found in iron ore is not well known. Based on results for synthetic samples of goethite (α-FeOOH) and hematite (α-Fe 2 O 3), it can be inferred that phosphorus occurs, probably, in the form of phosphate adsorbed on the particle surface or occluded in the micropores.
