beneficiation of magnetite iron ore

May 01, 2014 May 01, 2014 In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and beneficiation

    PROCESS FOR BENEFICIATING MAGNETITE IRON ORE

    Magnetite (Fe 3 O 4) (molecular weight 231.55 ) contains 72.36 percent iron. Even if all of the iron appeared as magnetite, no more than about 34.5 to 48.4 percent of the ore would consist of magnetite. Since industrial concentration of this ore is accomplished with magnetic separators, only the iron occurring as magnetite can be recovered
