procedure of magnetite powder manufacturing,Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores. With the chemical formula Fe3O4, it is one of the oxides of iron. Magnetite 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.

Magnetite Uses - Education - Micrex Development Corp

Magnetite is an essential part of the "heavy media" process in coal mining. In the form of a very fine powder, it is added to water to form a heavy media slurry that has a higher specific gravity than water alone. When coal from the mine is pulverized and added to the slurry, the heavier waste materials, such as rock particles,.

US5958282A - Low cost method for manufacturing ferrofluid - Google

A typical ball mill grinding process starts with commercially-available magnetic powder, such as magnetite powder, in which the particles are of "micron size", e.g. about 0.15 to 0.3 microns (i.e. about 150 nm to 300 nm). The commercially-available magnetite particles are then ground to reduce their size about 90%, to about.
