For example, a dense medium can be a chemical such as tetrabromoethane which has a specific gravity of 2.96 or a dense medium can be made using very fine particles of magnetite or ferrosilicon suspended in water as a slurry. The SG values of the slurries made from magnetite and ferrosilicon can be as high as 2.5 and 3.2 respectively.

The rejected slimes (Fe(T):28%) of the Krivoy Rog province, Ukraine and mines of Brazil (Fe(T):44%), Gossan ore tailings (Fe(T):45%), were upgraded by conventional beneficiation (utilizing teetered bed separator, gravity concentrator, and magnetic separator) and cyanidation to produced concentrate of 57%–65.54% Fe(T) with …
Among options to address this issue is a significant switch in iron ore mining focus from hematite towards magnetite. Magnetite ores tend to have a much lower Fe content but are often suitable for significant beneficiation, in part because magnetite is magnetic, enabling easier separation. These can often be beneficiated to DR-grade.
Magnetic separation is successfully applied for the beneficiation of igneous apatite deposits, which is abundant in ferriferous minerals, such as magnetite or titanomagnetite. The beneficiation of …
