Separation of aluminium and preparation of powdered DRI from lateritic iron ore based on direct reduction process

Abstract: Lateritic iron ore has not been used effectively due to excess content of multiple metals. In this work, separation of aluminium from a high-aluminium lateritic iron ore was achieved by the process of 'direct reduction with sodium sulfate-magnetic separation', with a powdered direct reduced iron (DRI) produced. It is found that the presence of 12% sodium sulphate during reductive roasting significantly improves separation of iron and aluminium in magnetic separation: the total iron grade (TFe) of powdered DRI … Show more
