Experimental and Commercial Magnetic Roasting

CIM Bulletin, 1961

THE USE of higher grade charges in blast furnaces in the form of sintered or pelletized concentrates has been increasing rapidly . The question of beneficiation of iron ores for this purpose is therefore receiving much attention as more deposits a re developed. Many iron ores may respond well to magnetic roasting procedures followed by magnetic concentration, however, in most cases other more standard ore dressing methods a re competitive and cheaper. For magnetic roasting as applied to iron ore beneficiation, the present question is "Can it be economically justified in situations where it appears to produce good results ?" The following collection of information on the general status and operations of magnetic roasting methods may be helpful in considering this question
