[0002] In the process of ore processing, flotation is an important mineral processing method, which is widely used in the separation of various metal ores, non-metallic ores, coal and other resources. Flotation technology mainly relies on the difference in physical and chemical properties of the mineral surface. By adjusting the pH value in the slurry and adding flotation agents, selective wetting and adhesion between the target mineral and the gangue mineral or other useful minerals are generated, thereby achieving the separation of minerals.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides an automatic flotation system for antimony ore. Figure 1-Figure 5 As shown, it includes a flotation bin 1, a material bin 2 is installed on one side of the flotation bin 1, a stirring assembly 3 is installed on the top of the flotation bin 1, and a flotation assembly 4 is also installed on one side of the upper part of the flotation bin 1. The stirring assembly 3 includes a stirring motor 31, and the output shaft of the stirring motor 31 is connected to a driving rod 33 through a transmission belt 32. The bottom end of the driving rod 33 is connected to a stirring rod 11, and a stirring blade 12 is installed on the outer wall of the stirring rod 11. The interior of the flotation bin 1 is divided into a mixing bin 13 and a concentrate bin 14, and the stirring rod 11 is located inside the mixing bin 13.

[0026] In this embodiment, a feeding trough 21 is provided on the upper part of one side of the material bin 2 to facilitate the feeding operation.

[0027] Specifically, a feeding pipe 22 is connected to one side of the bottom of the material bin 2, a plurality of discharge ports 221 are arranged on the top of the feeding pipe 22, and a feeding pump 222 is installed at one end of the feeding pipe 22 to facilitate feeding.

[0028] Furthermore, the flotation assembly 4 includes a rotating shaft 41 , on which a plurality of scrapers 42 are mounted. Both ends of the rotating shaft 41 are mounted on the outer wall of the flotation bin 1 via fixing plates 43 , and the ends of the rotating shaft 41 are driven to rotate by the flotation drive motor 6 .

[0029] Furthermore, an air pump 5 is installed on the top of the flotation tank 1, the output end of the air pump 5 is connected to a ventilation pipe 51, the bottom end of the ventilation pipe 51 is connected to a ventilation plate 52, the interior of the ventilation plate 52 is hollow, and a plurality of nozzles 521 are provided on the top surface to facilitate the gas to be sprayed out.

[0030] Furthermore, the driving rod 33 is rotatably connected to the outer wall of the flotation chamber 1 through the bearing seat 34, so as to drive the stirring rod 11 to rotate.

[0031] Furthermore, a flotation port is provided at the top of the mixing bin 13, and the bottom end of the scraper 42 is flush with the top flotation port of the mixing bin 13, so as to facilitate scraping out the floating minerals.

[0032] Furthermore, the nozzles 521 are arranged at equal intervals to facilitate uniform air injection.

[0033] When the automatic flotation system of antimony ore of the utility model is used, the antimony ore to be processed is first added to the material bin 2 through the feeding trough 21. The stirring motor 31 is started, and its output shaft drives the driving rod 33 to rotate through the transmission belt 32, thereby driving the stirring rod 11 and the stirring blade 12 to fully stir and mix the materials inside the mixing bin 13. This step ensures the uniform contact between the mineral particles and the flotation reagent, laying the foundation for the subsequent flotation process. The flotation drive motor 6 is started, and the rotating shaft 41 is driven to rotate, thereby driving the scraper 42 to rotate and scrape on the top of the mixing bin 13. At the same time, the air pump 5 is started, and gas is introduced into the mixing bin 13 through the ventilation pipe 51 and the ventilation plate 52. The gas is evenly ejected through the nozzles 521 arranged at equal intervals, contacts with the stirred mineral particles, and promotes the flotation separation of the mineral particles. In this process, the action of the flotation reagent makes the surface of the target mineral particles hydrophobic, and after combining with the bubbles, it floats to the top of the mixing bin 13 to form a foam layer.

[0034] The bottom end of the scraper 42 is flush with the top flotation port of the mixing bin 13. As the scraper 42 rotates and scrapes, the floating mineral foam layer is scraped and introduced into the concentrate bin 14 for collection. The gangue minerals and other impurities that fail to float remain in the mixing bin 13 and are eventually processed by the tailings treatment system.
