Magnetite an overview ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it is magnetic.The formula could be written as Fe 2 +Fe 3 +2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

Magnetite Wikipedia

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

Taconite Wikipedia

To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux. As a last step, it is rolled into pellets about 10 millimeters in diameter that contain about 65% iron.
