Manganese Ore Concentration by Flotation. The slime fraction of the ore overflowed by the hydraulic classifier and by the rod-mill spiral classifier is thickened in a Spiral Rake Tray Thickener for treatment by flotation. The …

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

The earliest attempts to float iron oxide minerals involved the use of anionic collectors such as oleic acid or sodium oleate. Such a process was used at the Cuyuna Range plant which processed manganiferous iron ore in 1931. One of the successful applications of anionic flotation process was the iron ore flotation plant at Marquette county ...

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export.
