The beneficiation of low grade iron ores is being accomplished using a number of different techniques, see U.S. Pat. Nos. 3,337,228 and 3,502,271 including washing, jigging, heavy media separation, flotation and magnetic separation. Ore concentrates thus obtained typically contain from 62 - 69% of iron and between 5 - 10% of silicon dioxide.
