Iron ore Wikipedia

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.

Processes for phosphorus removal from iron ore a review

2.1 Phosphate occurrences. Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite. Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid (Xia et al., 2011).The most frequent and important constituent of the class of phosphates is

Removal of phosphorus from iron ores by chemical leaching

Dec 01, 2006· Alkali-leaching and acid-leaching were proposed for the dephosphorization of Changde iron ore, which contains an average of 1.12% for phosphorus content. Sodium hydroxide, sulfuriced, hydrochloric and nitric acids were used for the preparation of leach solutions. The results show that phosphorus occurring as apatite phase could be removed by alkali-leaching, but those occurring in the iron
