Removal of Phosphorus from High-Phosphorus Iron Ores by Sodium Roasting

Article Preview

Abstract:

The phosphorus removal from high-phosphorus iron ores by sodium roasting was studied. The effects of ratio of NaOH to NaCO3, roasting temperature and reaction time on the dephosphorization ratio were investigated. The results showed that the dephosphorization ratio can reach 80.1% under the conditions of ratio of NaOH to NaCO3 5:6, roasting temperature 1100°C, and reaction time 120min. After sodium roasting, the content of phosphorus in iron ore sample complied completely with the requirements of steel production.
