Description

Technical Field

[0001] The utility model relates to the technical field of copper tailings flotation, in particular to a high-efficiency flotation device for extracting copper concentrate from copper tailings. Background Art

[0002] Flotation involves the use of a surfactant (frother) that generates a large number of bubbles. When air is introduced into the water or air is introduced into the water due to agitation, the hydrophobic end of the surfactant is oriented toward the air side of the bubble at the air-liquid interface, while the hydrophilic end remains in the solution, forming bubbles. Another surfactant (usually a cationic surfactant, but also a fatty amine) acts as a collector and adsorbs onto the surface of the solid mineral powder. This adsorption is selective depending on the properties of the mineral. The basic principle is to utilize lattice defects on the crystal surface, with the outward-facing hydrophobic end partially inserted into the bubble. This allows the bubble to carry away the desired mineral powder during the flotation process.

[0003] In the prior art, the bubble scraping shaft in the flotation equipment is usually fixedly installed. When the height of the bubble scraping shaft needs to be adjusted, it needs to be disassembled, which is troublesome and affects the efficiency of the bubble scraping. Utility Model Content
