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.

The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 µm, by using WHIMS2.

Magnetic Separation: Magnetic separators are employed to separate magnetic minerals from non-magnetic ones. This is particularly useful for removing magnetite or other strongly magnetic minerals from the ore. Froth Flotation: Froth flotation is a commonly used method for separating fine particles of minerals. In iron ore beneficiation, froth ...

Because the crystal water in limonitic ores will report to the iron ore concentrate in magnetic separation, the iron ore concentrate grade is limited to about 52% Fe. Figure 9.17 shows an example of a flow sheet to upgrade a limonitic ore. The ore is mainly composed of limonite and quartz with a grade of about 40% Fe.
