Phosphorus Removal of High Phosphorous Oolitic Iron Ore

Phosphorus Removal of High Phosphorous Oolitic Iron Ore

A process with acid leaching followed by hydrogen based fluidized reduction and melt separation is presented for recovering DRI (direct reduced iron) from high phosphorus oolitic hematite in this study, and the aim of this study is to provide theoretical and technical basis for economical and rational use of high phosphorus oolitic iron ores.
