Wet magnetic separation of phosphorus containing phase

The solidified slag was crushed, milled and then separated by a wet magnetic method at 0·35 T. X-ray fluorescence, X-ray diffraction, scanning electron microscopy and image analysis were used to investigate the separation of phosphorus containing phase from the slag. Results show that nearly all the phosphorus was enriched in the C2S phase in the modified slag which was separated into two
