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

13/11/2020  The reduction degree (R) of iron ore is defined as the ratio of oxygen mass loss to the initial reducible oxygen mass in the hematite ore as shown in Eq. . As the experimental temperature is above 843 K, the reduction process of hematite takes place step-wise, with magnetite and wüstite as intermediates. When the hematite is completely reduced to magnetite and wüstite, the reduction

Magnetite Concentration Methods

The ore is lifted by elevator to the top floor of the mill and dumped into a bin of 1.5 cu. yds. capacity. The mill flow sheet follows on page 106. The crude ore carries magnetite, hematite, and pyrites in pegmatite and schistose material. The ore carries about 40 per cent. iron and the concentrate from 60 to 61 per cent. iron. The concentrate is roasted to remove sulphur.
