Therefore, the particle size ratio (i.e. ratio of coarse particle size to fine particle size) of feed material must be arranged to increase both the concentrate grade and recovery. The strongly magnetic particles were separated by a cross-belt magnetic separator at 2000 gauss magnetic field intensity prior to high-intensity magnetic separation.
Developments in the physical separation of iron ore ...
In magnetic separation, as the mass and the magnetic susceptibility of the particle are fixed, only the magnetic field intensity or gradient can be varied to change the magnetic force. This is why it is extremely important to create a magnetic field of high intensity and gradient for oxidized iron ores in order to achieve higher iron recovery.
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.

In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.
