Froth Flotation of Iron Ores

Froth Flotation of Iron Ores

02/01/2012· Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides 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,Iron ore slimes flotation - ScienceDirect,01/10/2010· The flotation recoveries reached 41.7% (weight) and 80.5% (iron) and the global recoveries were 17.9% (weight) and 33.4% (iron). The achieved Gaudin’s selectivity index was 23.9. 4. Conclusions. The target of producing a high grade iron ore concentrate from the final slimes of a mining operation, via cationic reverse flotation, was reached.Improving recovery of iron using column flotation of iron,,01/11/2020· Mechanical Flotation Cells: Castro and Peres (2013) Iron ore slimes (underflow) from itabirite ore desliming in hydrocyclone (101.6 mm in diameter) from Samarco.
