About this site

Magnetite is a 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 of ...

The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.

Understanding the high-grade iron ore market

Magnetite has a slightly higher Fe content as a mineral (72.36% vs 69.94% for hematite), and its ferromagnetic properties allow for relatively easy concentration using magnetic separation. The biggest differentiating factor in terms of value-in-use is the exothermic reaction of magnetite in the sintering and pelletizing processes, saving
