Some Problems in the Crushing and Grinding Stage of ...

Selective grinding refers to a kind of grinding phenomenon in which the ore fragmentation degrees is different in the grinding process due to the difference in hardness between minerals. The main purpose of the crushing and grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals.

Grinding - Mineral Processing

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
