12%A representative high-phosphorus refractory iron ore obtained from the Hubei province of China was used in the experiments. The chemical composition of the iron ore is shown in Supplementary Table SI. The ore mainly contained 46.31% Fe, 20.14% SiO 2, 6.03% Al 2 O 3, 2.46% CaO, and as high as 1.07% P.

Iron ores with phosphorus content lower than 0.07% P are commercially desired as they are suitable for use in iron production. As a consequence, a lot of research efforts have been focused on phosphorus removal from high-phosphorus iron ore [20, 24, 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48] in a bid to reduce the P content to …

The remaining high iron grade ore has a high phosphorus content and is unsuitable for iron and steel production without dephosphorisation treatment. Over 90% of Western Australian high grade iron ore has a phosphorus content in excess of 0.05% and the average phosphorus content is 0.15%.

The high phosphorus oolitic hematite ores are more amenable to dephosphorisation by physical separation than the limonitic ones (Jiang et al., 2008). Following beneficiation of such ore graded at 37.51% Fe and 0.88% P by spiral chute and shaking table, an iron concentrate with 58.67% Fe and 0.52% P at 51.93% recovery has been obtained. The ...

The X-Ray Diffraction (XRD) analysis of the raw iron found that iron mainly occurs in the form of hematite, with impurities including quartz ...

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. Goethite grains containing high levels of phosphorus are abundant in many iron ores and can be difficult to remove without also discarding valuable iron-containing units.

Due to the oolitic structure of the high phosphorus iron ore and the closely wrapping of apatite and hematite phases, an approach using jet mill was utilized to grind the ore to ultrafine 0.01 to 0.001 mm, which realizes the dissociation of apatite phase and hematite phase. Then in a laboratory scale rotary furnace, high phosphorus ores of different sizes …
