• Froth Flotation of Iron Ores Publications

    the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
