Problems solved by technology

However, as the ore particle size decreases, the flotation behavior of mineral particles will change fundamentally. The conventional flotation process can only deal with those that are floatable and easy to float. required minerals, but it is difficult to fully recover these useful fine-grained minerals

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in the figure, the nano-bubble flotation device of this embodiment includes a vertically arranged rectangular tubular casing 1, the lower end of which is connected to a funnel-shaped waste collection and discharge bucket 2, and the rectangular tubular casing One side of the upper end is provided with a foam discharge port 3, and the upper end of the rectangular tubular shell is also provided with a bubble scraper 4 that drives the foam to the foam discharge port; the outer side of the lower end of the rectangular tubular shell is also connected with a support frame 5 .

[0019] In this embodiment, the foam scraper 4 includes a belt 401, a foam scraper 402 arranged on the outer surface of the belt, a driving pulley 403 and a driven pulley 404 arranged on a rectangular tubular housing and matched with the belt, and a driving pulley. A thi...

Abstract

The invention discloses a nano-bubble flotation device comprising a rectangular tubular shell, a waste collecting discharge bucket and a bubble scraping device. A nano-foam generator is further arranged on the lower portion of the rectangular tubular shell and comprises a cavity, a horizontal partition plate, a conical filter plate and microflow pipes; the microflow pipes comprise inner pipes, outer pipes and copper foil coils; waterproof bearings are fixedly arranged at the two ends of the inner pipes, and rotating shafts are arranged in the waterproof bearings; and blades for shearing airflow discharged by the copper foil coils are arranged at the upper ends of the rotating shafts. The sizes of nano-bubbles generated by the nano-bubble flotation device can be controlled by controlling the diameters of micro-airflow channels and the rotating speed of a first motor, the sizes of the generated nano-bubbles are stable, the bubble volume is large, the flotation efficiency is high, and themineral recovery rate is high; and the nano-bubble flotation device is simple in overall structure and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a device for flotation using nano-bubbles. Background technique [0002] Foam flotation is often used to separate fine minerals. Compared with shaking table mineral separation, high gradient magnetic separation and oil accumulation, bubble flotation has better efficiency and lower cost. The main principle of the flotation method is based on the difference in the chemical properties of the surface of minerals and slag, using the natural hydrophobicity of the surface of mineral particles and the hydrophilicity of slag to separate minerals and impurities. [0003] With the continuous development and consumption of mineral resources on the earth by human beings, rich ore and easy-to-handle ore resources are decreasing day by day, while the demand for metal materials is increasing, so poor, fine and miscellaneous ores have to be mined and sorted. This type of ore must be gr...
