Jul 15, 2015 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 …
[email protected]Phosphorus associated with goethite in high-phosphorus ( 0.10 mass% P) iron ores was lowered to below 0.075 mass% P with a heat treatment at 300 or 350 C for 1 h followed by a sulphuric acid ...

Phosphorus (P) gets adsorbed in the iron ore by way of ion exchange mechanism of clay minerals and hydrated secondary iron oxide minerals. Its concentration is lesser in hard ores and blue dust types of ores, while the highest in case …

read moreBog ore often has a high phosphorus content (Gordon 1996, p. 57). The strength and hardness of iron increases with the concentration of phosphorus. 0.05% phosphorus in wrought iron makes it as hard as medium carbon steel. High phosphorus iron can also be hardened by cold hammering. The hardening effect is true for any concentration of phosphorus.

First, phosphate can be leached from iron ore by functional groups (bacterial metabolites) excreted by the cell, and secondly, biobeneficiation of iron ores can be selectively floated or flocculated by bacterial cells and/or their metabolites.
