Dephosphorization of High-Phosphorus Iron Ore

2015-3-31  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, dephosphorization of high-phosphorus iron ore through microbial process with three different

A hydrometallurgical process for the

A process is proposed for the dephosphorization of iron ore. The process consists of an integrated treatment for the removal of the phosphorus from the ore by leaching and further processing of the leach solution. Phosphoric acid is extracted by isoamyl alcohol (iAmOH) and stripped by nitric acid solution.

Gasification dephosphorization mainly occured from 10 min to 25 min at 1200°C. These findings leads to a new idea on the dephosphorization of a high -phosphorous iron ore, that is, decreasing the reduction temperature to retard melting of iron and simultaneously adding the additives to promote the dephosphorization of fluorapatite.
