iron ore resources have become a national priority. As per the recent national steel policy, our country will be producing about 110 million tons of steel per annum by 2020 requiring around 42 million tons of iron ore. The iron ore exports are projected to a level of 114 million tones and it amounts to total production of 300 million tons by 2020.

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.
