phosphorous removal from iron ore in solid state

phosphorous removal from iron ore in solid state. The distribution characteristics of phosphorus in the metallic iron, and the reduction behaviors of hematite and fluorapatite during solid-state reductive roasting of a phosphorus-rich (1.3 mass%) oolitic hematite ore were investigated in the temperature range of 900°C–1200°C.

Processes for phosphorus removal from iron ore - a review

Xu et al. investigated the phosphorus removal of oolitic hematite ore of high content of iron by applying a reductive calcination with dephosphorizing agent (Na 2 SO 4 and Na 2 CO 3). The calcined mass was subjected to two stages of magnetic separation and grinding. The phosphorus content dropped from 0.82% to 0.06% and iron from 43.65% to 60.23% with 87% mass recovery. Analysis showed that 20 ...

01/11/2019  1. Introduction. Australia’s iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).The phosphorus content of Australian iron ores is a particularly ...

Removal of phosphorus-rich phase from high

The iron-slag separation by super-gravity resulted in phosphorus being effectively removed from the iron-rich phase and concentrated as a phosphorus-rich phase at a temperature below the melting point of iron. The samples obtained by super-gravity exhibited obvious layered structures. All the iron grains concentrated at the bottom of the sample along the super-gravity direction, whereas the ...

Phosphorus in Steels – IspatGuru

18/09/2014  The iron (Fe) – P phase diagram is shown in Fig 1. Fig 1 Fe- P phase diagram. P is normally considered an undesirable impurity in steels. It is present in varying concentrations in iron ore, is retained in hot metal, but is eliminated early in the steelmaking process. P oxidizes readily and is removed from steel as P2O5, which is taken up by the oxidizing slag, before the oxidation of carbon ...
