specific Embodiment approach

[0018] The preferred embodiment of the vertically stacked column flotation device of the present invention is:

[0019] Including the primary flotation column, the middle flotation column and the tail flotation column, the three flotation columns are vertically stacked from top to bottom, connected end to end, the upper part of the primary flotation column is connected with the ore feeding device, and the The lower part of the tailing flotation column is connected with the tailings device, the ore feeding pipe of the middle flotation column is connected with the middle ore pipe of the primary flotation column, and the ore feeding pipe of the tailing flotation column is connected with the middle flotation pipe The medium ore tube of the selection column is connected, and the three kinds of flotation columns are respectively equipped with a concentrate tube, and the three concentrate tubes are combined or connected to the follow-up processing equipment separately.

[0020] The p...

specific Embodiment

[0026] Such as Figure 1 to Figure 4 As shown, the initial flotation column 1, the middle flotation column 2, the tail flotation column 3, the total support 4 and the total foam pipe 5 are composed of three flotation columns in series and vertically stacked, as figure 1 shown. Three of the flotation columns are fixed on the general support 4 according to this, the ore is fed from the primary flotation column 1, the middle ore enters the middle flotation column 2 and the tail flotation column 3 by gravity, and the tailings are fed from the tail flotation column 3 The bottom is discharged, and the concentrates of the three flotation columns can be combined into the total foam pipe 5. The ore feed of the primary flotation column 1 enters the bottom of the foam layer to realize countercurrent collision and fluidized flotation, and mainly collects fine particles that are easy to attach to the medium; the feed of the intermediate flotation column 2 is divided into two parts, and on...

Abstract

The invention discloses a vertically stacked column flotation device, which comprises a primary flotation column, a middle flotation column and a tail flotation column. The three flotation columns are vertically stacked from top to bottom and connected end to end. The upper part of the flotation column is connected with the ore feeding device, the lower part of the tailing flotation column is connected with the tailings device, the ore feeding pipe of the middle flotation column is connected with the middle ore pipe of the primary flotation column, and the ore feeding pipe of the tail flotation column It is connected with the medium ore pipe of the middle flotation column, and the three kinds of flotation columns are respectively equipped with concentrate pipes, and the three concentrate pipes are combined or separately connected with subsequent processing equipment. The short flotation columns with individual differences are arranged in a stacked arrangement, and the three separation mechanisms of foam flotation, foam layer separation and fluidized separation are combined to achieve differential separation for different feed particle size characteristics, and at the same time Reduce the probability of mineralized bubbles rising and falling off, and meet the requirements of full-grain separation. Changing the use limit of conventional flotation columns in roughing and sweeping can expand the use range of flotation columns.

Description

technical field [0001] The invention relates to equipment for froth flotation, in particular to a vertical stacked column flotation device. Background technique [0002] Flotation column is one of the main equipment used for froth flotation under gas-liquid-solid three-phase conditions. It is generally used in the beneficiation operation of mineral processing plants to improve the quality of concentrate. It is mainly composed of bubble generating device, ore feeding and dispersing device, flushing water device, flotation column body, foam collecting device and liquid level control device. The bubble generating device is generally installed at the bottom of the flotation column, and the bubbles generated rely on buoyancy to rise, while the ore feeding device feeds the slurry from the upper part of the flotation column, and the countercurrent collision between the bubbles and the target mineral particles is realized in the flotation column, and the bubbles displace the particl...
