Iron Ore Magnetic Separation

Wet Magnetic Separation of Cornwall Ore. During the dry magnetic separating tests on Cornwall ore, it became evident that this process of magnetic separation was not suitable for this ore, for the following reasons: Dust. The ore must be very dry in order to secure freedom of motion between the particles, or poor separation will result.

Coal Washing, Magnetic Separation & Processing

In comparison magnetite ore has lower iron content when mined of between 25% and 40% Fe and requires processing, or magnetic separation, to separate magnetic minerals from other minerals in the ore. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics.

Magnetite Concentration Methods

Magnetite ores occur in large bodies in almost all countries, and on account of the high iron tenor of the pure mineral, and the ease with which it is concentrated, its treatment forms one of the most important fields of magnetic separation. Magnetite (composition Fe3O4) has a specific gravity ranging from 5.0 to 5.1, and is sufficiently heavy to permit of its concentration from gangue by specific-gravity methods, …
