Magnetic-gravity separation of iron ore

Fe is combined not only with magnetite aggregates but with fine grade magnetite also. This is caused by the fact that on reducing the size by <50 mk, the magnetic susceptibility of magnetite particles sharply decreases and becomes comparable or less than that of aggregates of magnetite and rock-forming minerals. That is why beneficiation of iron

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

Rouging Corrosion

This type of rouge is the high temperature reaction product of steam with the iron in the stainless steel forming magnetite. The reaction appears to take place in two steps: 3Fe0 + H 2 O --> FeO + Fe 2 O 3 + H 2. FeO + Fe 2 O 3--> Fe 3 O 4. Some of the iron oxide may be replaced with nickel oxide, but the iron sesquioxide will control the color
