Removal of Phosphorous from Australian Iron Ores

Phosphorous is typically present in iron ore either in the mineral apatite Ca5 PO4 3OH or associated with the goethitic fraction of the ore In this paper we present results that show that phosphorous associated with the goethitic fraction can be removed with a heating pretreatment around 300C for 1 h followed by a caustic leach with 1 - 5 M NaOH or a leach with sulfuric acid at pH 05...
