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

The mineral content can double in a matter of minutes, changing the flow characteristics dramatically. The processes are complex, with many circulating loads. The operator not only has to think of what is coming, but also what is coming back. Grinding typically has two recirculating streams and flotation can have as many as 10.
