]. The ore is heated and reacts with oxidant or reductant during magnetizing roast process. Magnetism of weak magnetic iron-containing minerals is significantly enhanced while magnetism of gangue minerals almost remains. Thus, iron can be successfully separated according to magnetic differences of iron-containing minerals and gangue minerals. After magnetizing roast of siderite with O2 as oxidant, JIU......

used in the flotation of iron minerals [6-8]. However, the research work on flotation of carbonate minerals such as siderite (FeCO3) and their potential effect on iron ore flotation is lacking due... minerals and CaO as the activator for quartz. After flotation, iron concentrate with iron grade of about 65% and iron recovery of higher than 70% could be usually produced [15]. However, it was found......
