(1) The useful mineral and the gangue mineral are not sufficiently separated from the monomer; (2) It is not easy to suspend in the flotation machine, and the probability of collision with bubbles is reduced; (3) The coarse particles move in the slurry and encounter turbulent oscillations, causing them to fall off the bubbles. Measures: Minerals that can be dissociated at a relatively coarse particle size are often re-selected. When the treatment of flocculated minerals must be treated by flotation, the usual strengthening measures are: (1) strong collector collecting capability, and increasing the collector dosage appropriate to enhance the fixing strength of the particles and air bubbles. Sometimes use an auxiliary collector such as a non-polar oil; (2) Properly increase the amount of aeration to provide more suitable bubbles to create conditions for flotation of coarse particles; (3) Selecting flotation equipment suitable for coarse flotation, in order to prevent coarse particles from forming sediment in the flotation equipment, a shallow trough flotation machine with large floating lift and large internal circulation should be used; (4) The use of a higher concentration of pulp, which increases the concentration of the agent, can also cause the particles to receive a large lifting force. However, it should be noted that when the slurry concentration is too high, the flotation process will be deteriorated and the selectivity will be lowered.
