(1) The impeller diameter is increased, the linear speed is increased, which strengthens the ability to mix the pulp and reagents. (2) The impeller is designed into an umbrella-type impeller, which enhances the ability to mix the pulp and reagents, and also strengthens the circulation ability. (3) There is a deflector in the tank, with the impeller located in the deflector, the enhanced mixing ability causes a large negative pressure in the pulp operation, and the deflector reduces the negative pressure within a limited space, thereby accelerating the suction ability of the pulp and reagents, further strengthening the circulation ability of the pulp and reagents. (4) The umbrella-type impeller has a downward pressure during operation, which further accelerates the suction ability of the pulp, further strengthening the circulation ability of the pulp and reagents. (5) The deflector is equipped with a jet body at the bottom, where the pulp and reagents enter, and the circulation ability is further strengthened. The thorough mixing and circulation of the pulp and reagents mineralize the mineral surface, which is beneficial for flotation.
