Dephosphorization of High-Phosphorus Iron Ore Using ...

Results show that the three strains of A. niger could grow well in the broth, and effectively remove phosphate from high-phosphorus iron ore during the experiments. Meanwhile, the total iron in the broth was also increased. Acidification of the broth seemed to be the major mechanism for the dephosphorization by

Phosphorus Removal of High Phosphorus Iron Ore by Gas ...

2010-9-1  A 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

XPS and FTIR spectroscopic study on microwave treated high ...

2015-8-1  XPS survey scans of high phosphorus iron ore indicated the presence of Fe, O, Si, Ca and P (Fig. 13, Fig. 14, Fig. 15). It can be seen that the shift in the Fe (2p) peak binding energy corresponds to iron oxide as a main component of the iron ore whereas the shift in the O (1s) peak corresponds to oxygen, phosphate and iron oxides speciation.

REMOVAL OF PHOSPHORUS THROUGH ROASTING OF

2014-1-18  Muhammed and Zang (1989) have used nitric acid (6M) leaching for 24 hours of a magnetite iron ore containing 1 – 3 % P presented as apatite and have claimed a drop in phosphorus level below 0.05 %. The same authors have stressed that the main problem during leaching has been gypsum precipitation and the contamination of iron concentrate with sulfur. 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 HNO3 at temperatures between 10 and 60°C and duration of up to 30 hours. Leaching after roasting to 300°C has been tested with Australian iron ores rich in phosphorus present as apatite by Edwards et al (2011). Results have reported that up to 44 % of P can be removed without pre-heating when 1M sulfuric acid solution was used

2015-7-15  In this study, an energy-saving and environmentally friendly method to produce low-phosphorus molten iron from high-phosphorus oolitic hematite was experimentally investigated and theoretically analyzed. The results indicate that biomass char is a suitable reducing agent for the proposed method. In the direct reduction stage, the ore–char briquette reached a metallization degree of 80–82% ...

In the present study, roasting-induced phase change and its influence on phosphorus removal via leaching has been investigated for high-phosphorus iron ore. The findings indicate that phosphorus in the ore is associated with goethite and exists mainly in amorphous Fe3PO7 phase. The phosphorus remains in the amorphous phase after being roasted below 300°C. Grattarolaite (Fe3PO7) is found in ...
