Abstract: In response to the characteristics of high-phosphorus iron ore, which the complex symbiotic relationship between iron minerals and phosphate minerals in high-phosphorus iron ore and the difficulty in efficient utilization through conventional beneficiation methods. The roasting -leaching technology for iron extraction and phosphorus reduction was proposed with a view to achieving efficient utilization of high-phosphorus iron ore. This paper investigated a high-phosphorus certain iron ore with a TFe grade 60.81%, FeO content14.92%, and P content 0.71% extracted from Algeria. The experimental study on iron extraction and dephosphorization was carried out by oxidizing roasting-magnetization roasting-magnetic separation-leaching process. The magnetic roasting process conditions of oxidation temperature 1 050 °C, reduction temperature 520 °C, reduction time 25 min and H₂ concentration 50% were determined. The iron concentrate indexes of total Fe grade 65.50%, total Fe recovery 96.31% and P content 0.16% were obtained, which 77.46% of P removed. The experimental results offer guidance for iron extraction and dephosphorization of iron ore in Algeria.
