Description

Technical Field

[0001] The utility model relates to the technical field of tailings flotation, in particular to a tailings foam flotation structure for improving flotation efficiency. Background Art

[0002] Flotation refers to the use of surfactants-foaming agents that can generate a large number of bubbles. When air is introduced into the water or air enters the water due to the agitation of the water, the hydrophobic end of the surfactant is oriented toward the air side of the bubble at the gas-liquid interface, and the hydrophilic end is still in the solution, forming bubbles; another surfactant that acts as a capture agent (generally cationic surfactants, including fatty amines) is adsorbed on the surface of solid mineral powder. This adsorption has a certain selectivity depending on the nature of the mineral. Its basic principle is to use the lattice defects on the surface of the crystal, and the outward hydrophobic end is partially inserted into the bubble, so that during the flotation process, the bubble may take away the specified mineral powder to achieve the purpose of mineral selection. In the flotation process, both positive and reverse flotation rely on the generated foam to select minerals. Due to the small specific gravity, high viscosity and small slope of the flow channel, the foam fluidity is very poor, which seriously affects the flotation foam.
