The available reserves of high phosphorus oolitic iron ore [1] located in western Hubei are above 2 billion tons. The ore is considered as a chemical sedimentary iron ore, mainly composed of oolite and detritus. Specifically, oolite consists of oolitecore (quartz or iron material), collophane girdle, hematite, and limonite girdles.
Sep 01, 2010· 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 of slag structure were adopted for theoretical analysis.
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.

Bog 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.
