Recovery and separation of iron from iron ore using ...

The dry iron ore powder (-0.3 mm) is preheated in countercurrent with the hot off-gas originally from the suspension heating furnace via a number of cyclone stages, and then enters into the suspension heating furnace. The hot gases (about 700~900 °C) produced by the combustion of water gas simultaneously heat and transport the iron ore powder to the gas-solid cyclone separator. Then, under ...

A Look at the Process of Pelletizing Iron Ore for Steel ...

Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials from the iron content. This processing works to transform raw, mined iron ore into a concentrated powder suitable for pelletizing. In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites ...
