Dephosphorization technology of iron ores by

The feasibility and technology on dephosphorization from phosphorous iron ores by bio-leaching were investigated.The results show that Acidthiobacillus ferrooxidans(A.f) can remove phosphor from iron ores and nutrient medium without phosphorus is more effective for the removal than that with phosphorus.The addition of pyrite greatly improves the dephosphorization,and the lower initial pH of

Dephosphorization Treatment of High

Dephosphorization process of high phosphorus oolitic iron ore by acid leaching and leaching kinetics were investigated in the paper. The high phosphorus ore samples (51%T.Fe, 0.52%P) used in this work were analysed by SEM-EDS and XRD, which showed their oolitic structure and mineral phases.

Dephosphorization of High-Phosphorus Iron

Ore residues by energy-dispersive X-ray microanalysis and Fourier transform infrared spectroscopy indicated that the phosphate was obviously removed from the high-phosphorus iron ore. The optimization of the dephosphorization by these strains was also investigated, and the maximum percentages of phosphate removal were recorded at temperature 27-30 °C, initial pH 5.0-6.5, particle

Dephosphorization of Steels – IspatGuru

Iron ore additions can be helpful to maintain ideal FeO content to continue P oxidation in parallel with the decarburization. Kinetics of phosphorus removal. Though P equilibrium has been widely studied, the kinetics of P removal has not been studied to that extent. However, the same principles for other high temperature metallurgical reactions apply. When P dissolved in Fe contacts slag

05.01.2012· Phosphorus in the charge could be at higher than usual levels for DRI, HBI, pig iron, and hot metal, depending on the iron ore source. Some steels require particularly low P levels to avoid too high ductile/brittle transition temperature or tempering brittleness. From the equilibrium point of view, lower temperatures, high slag basicity, and high oxidation of the bath favor dephosphorization
