High-efficiency flotation method and its flotation equipment

Abstract

The invention discloses a column combined reinforced high-efficiency flotation method and flotation equipment thereof. The method comprises four processes, namely strong turbulence mineralization realized by a raw ore through mechanical stirring, static flotation realized by settled sands through counterflow mineralization, weak turbulence separation realized by bubbles through a rectification effect, as well as concentrate secondary enrichment and accurate scraping realization. In the flotation equipment, a bracket is arranged on the top of a cylinder body, a flat scraper is arranged on the lower side of the bracket; a feed pipe is arranged on a position in lower middle of the cylinder body; the outlet end of the feed pipe is connected with the lower end of a false bottom; the false bottom is connected with a rectification plate; an annular inflating pipe is arranged on the lower part of the cylinder body; a monomer rectification plate is connected to the inner wall of the cylinder body; a sleeve is sleeved outside a hollow shaft; and an impeller is connected with the lower end of the hollow shaft. By integrating the advantages of strong mineralization effect of a flotation machine and better separation environment of a flotation column, the defects of high turbulence degree of the traditional flotation machine and insufficient mineralization of the traditional flotation column can be overcome, reinforced high-efficiency flotation is realized, and adaptability to the flotation process is stronger. The column combined reinforced high-efficiency flotation method and the flotation equipment thereof can be applied to separation operation of coals, chemical minerals and the like.

Description

Technical field [0001] The invention relates to a beneficiation method and equipment, in particular to a flotation method and flotation equipment for realizing the method. Background technique [0002] The well-known flotation machine is a kind of flotation equipment commonly used in the field of mineral processing, and is widely used in the separation of non-ferrous metals, ferrous metals, rare and precious metals, coal, and chemical minerals. There are many types of flotation machines, and the differences are mainly manifested in the aeration method and stirring structure. The most widely used classification method is to divide the flotation machine into two categories according to the different aeration and stirring methods, namely, mechanical agitation flotation machines And inflatable flotation machine (Xie Guangyuan, "Mineral Processing", China University of Mining and Technology Press, August 2001). Mechanical agitation flotation machine is usually referred to as flot...

AI Technical Summary

Problems solved by technology

The separation environment of the flotation machine is poor but the mineralization effect is good, and the mineralization degree of the flotation column is weak but the separation environment is good. The present invention combines the advantages of the two to have good mineralization effect and good separation environment, and solve the problem of insufficient concentrate discharge methods that exist in both
