how magnetite is process of mining used

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, will sink and ...

Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining Process

Magnetite ore (Fe3O4) is a ferromagnetic mineral commonly used in magnetic separation coal washing processes.. Coal washing using magnetite is used to remove contamination from run-of-mine (ROM) coal, which usually contains rocks, middlings, used consumables and other contamination introduced by the mining process.

Magnetite - Wikipedia

Due to its high iron content, magnetite has long been a major iron ore. It is reduced in blast furnaces to pig iron or sponge iron for conversion to steel. Audio recording using magnetic acetate tape was developed in the 1930s. The German magnetophon utilized magnetite powder as the recording medium. Following World War II, 3MCompany continued work on the German design. In 1946, the 3M researchers found they could improve the magnetite-based tap
