Iron Ore Benefication Removal Of Phosphorous

The results show that phosphorus occurring as apatite phase could be removed by alkalileaching, but those occurring in the iron phase could not. Sulfuric acid is the most effective among the three kinds of acid. 91.61 phosphorus removal was attained with 1 sulfuric acid after leaching for
