FFERRO-ALOY RECUPERATION METHOOD FROM SLAG

Process comprises crushing and grinding to below 2mm, e.g. slag from the production of carburised ferrochrome. The up to 200mm slag fraction contains: SiO2 29.74, Al2O3 23.60, MgO 32.39, CaO 3.14, Cr2O3 3.89, Mn 3.10, TiO2 0.52, P2O5 0.13, and S 0.459 per cent respectively. The crushed material is t...

Zusammenfassung:	Process comprises crushing and grinding to below 2mm, e.g. slag from the production of carburised ferrochrome. The up to 200mm slag fraction contains: SiO2 29.74, Al2O3 23.60, MgO 32.39, CaO 3.14, Cr2O3 3.89, Mn 3.10, TiO2 0.52, P2O5 0.13, and S 0.459 per cent respectively. The crushed material is then sepd. in a magnetic field of 600-2000 Oersteds strength.
