Dephosphorization of High-Phosphorus Iron Ore Using ...

High-phosphorus iron ore is traditionally dephosphorized by chemical process with inorganic acids. However, this process is not recommended nowadays because of its high cost and consequent environmental pollution. With the current tendency for development of a low-cost and eco-friendly process, deph

2015-3-31 · High-Phosphorus Iron Ore. The ore sample used in this study was obtained from western Hubei province, China. The ore sample was ground to a particle size of 0.07–0.15 mm. X-ray diffraction (XRD) analysis showed that the sample was mainly composed of hematite (α-Fe 2 O 3) and a small quantity of quartz and apatite (Ca 2 PO 4 Cl and Ca 5 (PO 4) 3 F). The main

Dephosphorization Treatment of High Phosphorus Iron

This paper proposes a novel process for the pre-treatment of high phosphorus iron ore by pre-reduction, air jet milling and screening methods. The dephosphorization behavior was evaluated as a function of such parameters as the milling gas kinetic energy, E k and specific energy consumption, E sp. At a fixed milling gas kinetic energy, the ...

Dephosphorization of iron - ScienceDirect

Melted iron, Puddled iron, The total dephosphorization is 61 per cent., of which 46 per cent. is due to the action of fusing it on the bed of the furnace with oxide of iron. Only 15 per cent., therefore, is due to further oxidation an4 to liquation. Special Dephosphorization in Puddling with Manganiferous Iron.q.
