Phosphorus Removal of High Phosphorus Iron Ore by Gas

Sep 01, 2010A new method (gas-based separation plus melt separation) has been proposed to remove phosphorus of the high phosphorus iron ore which was 1.25% of phosphorus content and 50.0% of iron content. HSC chemistry package and the coexistence theory of slag structure were adopted for theoretical analysis.

Removal of Phosphorus From High Phosphorus Iron Ores

May 01, 2011In order to effectively remove the phosphorus from high phosphorus iron ores, while reduce the amount of acid and the iron losses, phosphorus will be removed in the form of soluble phosphate salts by selective hydrochloric acid leaching in this research.

Removal of phosphorus from iron ores by chemical

高达10%返现Dec 01, 2006The results show that phosphorus occurring as apatite phase could be removed by alkali-leaching, but those occurring in the iron phase could not. Sulfuric acid is the most effective among the three kinds of acid. 91.61% phosphorus removal was attained with 1% sulfuric acid after leaching for 20 min at room temperature.

REMOVAL OF PHOSPHORUS THROUGH ROASTING OF

An efficient removal of phosphorus down to 0.05 % from high P iron ores is reported by Forssberg and Adolfson (1981). In this study P was also present mainly as apatite and its leaching was carried out with 2M HCl and 2 6 M HNO 3 at temperatures between 10 and 60°C and duration of up to 30 hours.

Dephosphorization of High-Phosphorus Iron Ore Using

Scanning electron microscopy of ore residues revealed that the high-phosphorus iron ore was obviously destroyed by the actions of these strains. 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.

Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden. A concentrate of sinter, moist, and without treatment was used. Chemical analysis showed the composition of 0.98% phosphorus (as P 2 O 5 22.25%) and 60.85% iron. Nitric acid was chosen due to the low reactivity of the acid with the
