The characteristics of strong magnetic minerals have influence on the magnetic separation process for following fields:

1. Because magnetite and other magnetic minerals have strong magnetism, fine crusher can adopt them by lower magnetic field.

2. The particles of magnetite will save magnetism as soon as magnetization. When particles are fine, particle will attract each other into a magnetic corporation or flux. Magnetic group is easy to disperse; it will lower the grade of the magnetic product. If the existence of magnetic ore grade homework group, the classification efficiency is reduced. This is the unlucky influence of the magnetic gathering. In this situation, demagnetizer can be used to eliminate residual magnetism destroyed magnetic gatherings.

3. Magnetic micro-particles of magnetite particles is weak, suffered resistance is still in the water activities, thus accepting to take over demand for larger magnetic, while the water washed away easily to form a metal drain away. Be seen that the grinding process to try to cut through the mill.
