Magnetic Concentration Of Magnetite

Magnetite Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces

A diagram of the magnetic concentration process is shown in Figure 1. In dry magnetic concentration, the ore is loaded onto the upper drums of a magnetic separator, which contain open permanent magnets that generate a field with an intensity of about 90 kiloamperes per meter (kA/m) on the surface of the drum. The magnetite ore is attracted to

Kinetics of hematite to magnetite transformation by

The transformation of weakly magnetic hematite to magnetite is a promising technique that can enhance the efficiency of magnetic separation of hematite quartzite. The transformation of hematite into magnetite involves the partial reduction of Fe(III) to Fe(II) and converting the rhombohedral crystal system of hematite into cubic of magnetite.

Biologically formed nanoparticles of the strongly magnetic mineral, magnetite, were first detected in the human brain over 20 y ago [Kirschvink JL, Kobayashi-Kirschvink A, Woodford BJ (1992) Proc Natl Acad Sci USA 89(16):7683–7687]. Magnetite can have potentially large impacts on the brain due to its unique combination of redox activity, surface charge, and strongly magnetic
