Problems solved by technology
Among these useful minerals, some of them cannot be recovered due to technical reasons, and some of them can be recovered under the existing mineral processing technology conditions, but they have not been implemented due to high production costs.
[0003] There are also corresponding low-energy or non-powered mineral processing equipment on the market now, and the flotation column is one of them. Compared with the traditional mechanical agitation flotation machine, the flotation column has the advantages of simple structure, high efficiency and energy saving, but its price is expensive. In actual production, the bubble generator is easy to block and is not suitable for the reselection of tailings products, so it is difficult to be popularized and utilized in the reselection of tailings products

Embodiment Construction
[0016] The upper part of the flotation cell body of the present invention is a cuboid, and the lower part is a cone. The bottom of the slurry inlet pipe located in the center of the flotation tank is closed, the bottom of the slurry inlet pipe is in the shape of an inverted cone, and the slurry outlet on the side wall is in the shape of a long strip. There is a cavity inverted quadrangular pyramid stirring box arranged at the bottom of the slurry inlet pipe, and the upper part of the slurry inlet pipe is connected with an air inlet pipe, and a gate valve is arranged on the air inlet pipe. In the flotation cell body, there are three layers of screens, the upper, middle and lower layers, and the aperture of the screens is 20mm. The height of the flotation liquid level is controlled by moving the liquid level regulating device up and down to adjust the gate valve.
[0017] The invention can obtain the aeration and stirring functions required for flotation only by relying on the ...

The invention relates to a mineral dressing flotation technology, in particular to a simple unpowered flotation device. A flotation column is expensive in the market nowadays, and a bubble generator is easily blocked in practical production and is not applicable to the reelection of tailing products. The flotation device comprises a flotation tank in which a stock inlet pipe is arranged; the bottom end surface of the stock inlet pipe is closed; the side wall of the bottom of the stock inlet pipe is provided with a stock outlet; the upper part of the stock inlet pipe is connected with an air inlet pipe; the bottom of the stock inlet pipe is provided with a stirring box; a screen mesh is arranged in the flotation tank; and a liquid level regulating device communicated with the flotation tank is arranged beside the flotation tank. The simple unpowered flotation device solves the problems existing in the flotation column and is worth promoting and utilizing.
Description
technical field [0001] The invention relates to ore dressing flotation machine technology, in particular to a simple non-powered flotation device. Background technique [0002] According to statistics, the total recovery rate of mineral resources and the comprehensive utilization rate of associated mineral resources in my country are about 30% and 35% respectively, that is, a large amount of useful minerals are discharged together with the tailings. Among these useful minerals, some cannot be recovered due to technical reasons, and some of them can be recovered under the existing mineral processing technology conditions, but they have not been implemented due to high production costs. [0003] There are also corresponding low-energy or non-powered mineral processing equipment on the market now, and the flotation column is one of them. Although the flotation column has the advantages of simple structure, high efficiency and energy saving compared with the traditional mechanic...
