Mechanism of phosphorus removal in beneficiation of
2012-11-28 Abstract: High phosphorous oolitic hematite ore is one of typical intractable iron ores in China, and the conventional beneficiation methods are found to be impracticable to remove phosphorus from the ore effectively. Better beneficiation index were gotten by direct reduction roasting with dephosphorization agent followed by two stages of grinding and magnetic separation. P content decreases from 0.82% in the raw ore to 0.06% in the magnetic concentrate, and the total iron grade increases from 43.65% to 90.23%, the recovery of iron can reach 87%.

Beneficiation of Low-Grade and High-Phosphorus Iron
2019-5-16 Deposits of low grade and high-phosphorus iron ores are spreading globally, however, the usage of this kind of deposits in the manufacturing of steel bounded because of the high-phosphorus content as well as depression of iron in which affect the quality of the produced steel.

2015-1-1 Shen et al. (2012) also found that acidophilic bioleaching microorganisms effectively bioleach phosphorus from iron ore when they added high-phosphorus iron ore and elemental sulfur to municipal wastewater to make an iron ore slurry. Apatite was the main phosphorus mineral in the iron ore and the wastewater contained native sulfur-oxidizing bacteria.

2019-2-2 Due to the low percentage of phosphorus (usually less than 3% P) in these ores classified as high-phosphorus iron ores, powder XRD often employed to determine and quantify crystalline phases in ores, is seldom useful in providing the vital insight into the bonding and local chemical environment around the phosphorus atom(s) in high-phosphorus iron ores.

Characterisation of phosphorus and other impurities
2019-11-1 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 serious problem.

The phosphorus in high-phosphorus (>0.1% P) iron ores from the Pilbara area of Western Australia is mainly associated with the goethite fraction of the ore. Physical separation methods and simple leaching processes do not remove sufficient phosphorus from the ores to meet market specifications of 0.075% P.
