Production of Pig Iron from Magnetite Ore–Coal

Magnetite ore–coal composite pellets with about 10, 15 and 20mm diameter were rapidly smelted to produce pig iron by microwave heating in N 2 gas. A microwave generator with 5kW maximum power at 2.45GHz was employed. Carbon content in pig iron was about 2mass% near the liquidus line in the Fe–C system. Slag was easily separated from pig iron.

ISO 8833:1989(en), Magnetite for use in coal preparation ...

In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and the presence of gangue minerals may lower the relative

The application of magnetite for coal preparation in ...

Finely ground magnetite, a dense form of iron oxide, is used in the preparation of the heavy medium suspensions used in the separation units. The average magnetite loss from a large heavy medium coal-cleaning facility can be as large as 10,000 to 13,000 tons per year, representing nearly one million dollars of annual operating costs.
