The selective HCl leaching method was used to remove phosphorus from high phosphorus iron ores. The hydroxyapatite in high phosphorus iron ores was converted into soluble phosphate during the process of HCl leaching. The effects of reaction time, particle size, hydrochloric acid concentration, reaction temperature, liquidsolid ratio and stirring strength on the dephosphorization ratio were studied. The results showed that the dephosphorization ratio can exceed 98% under the conditions of reaction time 30-45 min, particle size ＜0147 mm, hydrochloric acid concentration 25 mol/L, reaction temperature 25 ℃, liquidsolid ratio 5∶1 and stirring strength 502-1276 s-1. After dephosphorization reaction, the content of phosphorus in iron ore complied completely with the requirements of steel production.
