Floatation apparatus and floatation method for promoting floating of coarse particle lean intergrowth

Abstract

The invention discloses a floatation apparatus for promoting the floating of coarse particle lean intergrowth. The floatation apparatus comprises a groove body, wherein a mineralization system is arranged in the groove body, the groove body is connected to a foam chute, and is downward connected to a tapered bottom, a floatation ore pulp inlet pipe extends into the groove body, a coarse particle precipitation box is arranged in the cavity formed by communicating the groove body and the tapered bottom, the bottom portion of the coarse particle precipitation box is provided with a row of coarseparticle discharge holes for coarse particle outflow, each coarse particle discharge hole is provided with a gravity valve, an ore pulp inlet and a wake outlet are arranged in the coarse particle precipitation box, the bottom portion, outside the coarse particle precipitation box, of the tapered bottom is connected to a circulating liquid outlet pipe, the circulating liquid outlet pipe is connected to a circulating pump, and the circulating pump is connected to the mineralization system. The invention further discloses a corresponding floatation method. According to the present invention, by adopting the technical scheme, the grinding fineness can be reduced while the same or even high coarse particle floating rate can be achieved, such that the production capacity of the grinding machinecan be increased, the energy consumption required for grinding is reduced, the energy-saving effect is achieved, and the mineral separation cost can be significantly reduced.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, which is used in the flotation separation process of metal minerals and non-metal minerals, and can also be used in the flotation separation process of coal beneficiation. Background technique [0002] Flotation technology is one of the most commonly used technologies in mineral processing technology and is widely used in mineral processing technology worldwide. Flotation technology is based on the difference in surface properties between mineral particles and gangue particles. After hydrophobic treatment is performed on the surface of gangue or mineral particles, the buoyancy of air bubbles is used to float the mineral or gangue particles, thereby realizing the separation of gangue and minerals. [0003] In the flotation process of minerals, the flotation of coarse-grained and poor contiguous bodies of oxidized ore has always been a difficult problem, and its flotation methods and equi...

Problems solved by technology

[0011] The second type of existing flotation equipment is an inflatable flotation column. The flotation column changes the flotation function from horizontal to vertical placement, which greatly shortens the beneficiation process. The flotation column technology is mainly based on China University of Mining and Technology 97236893.0 Fluid static micro-bubble flotation column and Central South University 01145542.X are technical representatives. The flotation column has a relatively large length and diameter, and the foam rises for a long time, and the coarse particles fall into the tank seriously, which is not conducive to the flotation of coarse particles and poor conjoined organisms.

[0012] The above three flotation technologies and equipment have their own advantages, but none of them can fundamentally improve the floating capacity of coarse particles and poor contiguous organisms.
