    Characterisation of phosphorus and other impurities in

    Nov 01, 2019· Phosphorus is one of the most deleterious elements in iron ore as it followsiron during downstream reduction processes,forming iron phosphides that make steel brittle. Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 0.07–0.08 wt-% P on the iron ore feed.

    Characterization studies on Agbaja iron ore a high

    Feb 02, 2019· The acceptable levels of P in hot metal range from 0.08 to 0.14 [ 4 ]; hence, iron ores for steelmaking with very low phosphorus contents are desirable. 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 ].
