According to the test, the particles usually need to be ground to a diameter of about 100 mm to release minerals from each other. When the particles are less than about 10 mm, this is not conducive to the flotation effect. Grinding operations are very power-hungry, which is another reason to avoid excessive grinding. Grinding circuit
