Description

Technical Field

[0001] The utility model relates to the technical field of flotation of gold and silver associated with sulfide ores, in particular to a flotation device for recovering gold and silver associated with sulfide ores. Background Art

[0002] The flotation machine for gold and silver associated with sulfide ores is a device used to extract useful minerals such as gold and silver from sulfide ores. This type of flotation machine mainly includes a flotation tank, an agitator, a bubble generator, a scraper collector, a reagent adding device, etc. By adding reagents to the flotation machine and using bubbles to separate useful minerals such as gold and silver in the sulfide ore from other non-useful minerals under stirring, the purpose of flotation separation and extraction of useful minerals is achieved. The flotation machine is widely used in metal mines and beneficiation plants and is one of the indispensable equipment in the flotation process of sulfide ores.

[0003] In the flotation process of gold and silver associated with sulfide ores, it is difficult to control the addition of reagents and bubbles. The size, density and distribution of bubbles have an important influence on the flotation effect. However, the operation of controlling the parameters of bubbles is complicated. Excessive addition of reagents will increase the amount of bubble generation, resulting in foam overflow. The overflow phenomenon will cause the bubbles to exceed the holding capacity of the flotation cell, causing the foam to overflow from the cell and may take away useful minerals, affecting the flotation effect. The flotation machine for gold and silver associated with sulfide ores needs to control the overflow phenomenon to improve the flotation effect and operational stability.

[0004] At present, the patent with the publication number CN201094935Y discloses a flotation machine, which is composed of a motor, a gate, a bearing, a scraper shaft, a scraper, a tank body, a machine base, and an agitator. On the left bottom of the tank body, dampers are arranged in front and rear of the outer periphery of the agitator impeller. The damper is a square steel plate which is perpendicular to the tank body and the circular arc trapezoidal steel plate and is fixedly connected to the inner side of the circular arc trapezoidal steel plate. Although the above device solves the problem of floating out various non-ferrous metals from mineral powder.

[0005] However, the above technical solution still has the following problems:

[0006] When the existing flotation machine is performing flotation, the bubble generator and the dosing device at the bottom of the mixer are placed on the side. When the mixer is stirring slowly, the catalyst and water added to the flotation machine cannot be completely mixed, and the foam generated by the catalyst and bubbles is difficult to control, and overflowing foam is prone to occur. The overflowing foam phenomenon causes a large amount of foam containing gold and silver to overflow the collection tank, causing losses and affecting the flotation effect. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, a flotation device for recovering gold and silver associated with sulfide ores comprises a flotation cell body 1, a scraper 2 installed on one side of the flotation cell body 1 and a collecting tank 3 installed on one side of the flotation cell body 1, a bubble pipe 6 is installed in the flotation cell body 1, one end of the bubble pipe 6 is connected to an air pump 7, a stirring device 5 is sleeved on the outer side of the bubble pipe 6, a gear belt 505 is sleeved on the outer side of the stirring device 5, and a driving motor 9 is connected to the other end of the gear belt 505.

[0024] like Figure 1 As shown, the flotation equipment for recovering gold and silver associated with sulfide ores in the utility model is similar to the existing flotation machine structure, such as the flotation machine disclosed in the patent publication number CN201094935Y. The main improvement of the utility model is to make the flotation machine dosing more uniform and the bubble generation easier to control, such as Figures 1 to 5As shown, when the flotation device for recovering gold and silver associated with sulfide ore is used, the sulfide ore containing gold and silver is placed in the flotation tank body 1, the bubble pipe 6 is controlled to pump water and catalyst into the flotation tank body 1, the drive motor 9 is turned on, the drive motor 9 drives the gear belt 505 and the stirring device 5 to rotate, so that the sulfide ore containing gold and silver forms fine particles, the sulfide ore containing gold and silver combines with the catalyst, the sulfide forms tailings and sinks to the bottom of the flotation tank body 1, the gold and silver particles are driven by the foam to float to the surface, and the scraper 2 removes the gold and silver particles. The foam of gold and silver particles is scraped into the collecting tank 3 to complete the flotation. During the flotation process, the air pump 7 can be controlled to pump air, and the gas continuously enters the flotation tank body 1 from the bubble pipe 6 to drive the foam to float continuously. In the flotation process, the catalyst and water are continuously added through the bubble pipe 6. The stirring device 5 is located in the middle position to evenly stir the bubbles, water and catalyst. The foam in the flotation tank body 1 is more uniform and controllable. The filling of medicine, water or air can be performed at any time to interfere with the generation of foam and improve the flotation effect of gold and silver associated with sulfide ores.

[0025] like Figure 1 As shown, an F-type support frame 4 is fixedly connected to one side of the top of the flotation tank body 1, the outer side of the bubble pipe 6 is sleeved on the upper horizontal side of the F-type support frame 4, the outer side of the stirring device 5 is sleeved on the lower horizontal side of the F-type support frame 4, and a bearing 504 is installed between the lower horizontal side of the F-type support frame 4 and the stirring device 5.

[0026] Specifically, this arrangement allows the stirring device 5 and the bubble duct 6 suspended in the flotation tank body 1 to be fixed, and the stirring device 5 and the F-type support frame 4 can rotate through the bearing 504. The lower end of the stirring device 5 is fixed by the gear belt 505, so that the stirring device 5 can be fixed to the flotation tank body 1 and can also rotate. There is a gap between the stirring device 5 and the bubble duct 6 to avoid affecting the rotation of the stirring device 5.

[0027] like Figure 1 As shown, the stirring device 5 includes a hollow pipe 501, a connecting plate 502 and a fixing plate 503, the outer ring of the bearing 504 is fixedly connected to the F-type support frame 4, the inner ring of the bearing 504 and the outer ring of the bearing 504 have a hollow pipe 501, the bottom of the hollow pipe 501 is connected to the connecting plate 502, and the bottom of the connecting plate 502 is fixedly connected to multiple fixing plates 503, the hollow pipe 501 is sleeved on the outside of the bubble pipe 6, and the gear belt 505 is sleeved on the outside of the hollow pipe 501.

[0028] Specifically, by setting the bubble pipe 6 in this way, water, medicine and gas can be pumped into the bottom of the center of the stirring device 5, the hollow pipe 501 is driven to rotate by the gear belt 505, and the connecting disk 502 and the fixing plate 503 at the bottom rotate to break the sulfide ore containing gold and silver into fine particles, and evenly stir the water, medicine and gas, thereby improving the effect of controlling the generation of foam.

[0029] like Figure 1 As shown, a grinding block 101 is fixedly connected to the bottom of the flotation tank body 1.

[0030] Specifically, when the fixing plate 503 is arranged to break the sulfide ore containing gold and silver, the grinding block 101 can help the fixing plate 503 to break and grind the sulfide ore containing gold and silver more quickly, thereby improving the crushing effect of the stirring device 5 .

[0031] like Figure 1 As shown, the outer side of the bubble pipe 6 is connected to a water pipe 8, and the outer side of the water pipe 8 is connected to a drug delivery port 801.

[0032] Specifically, through this arrangement, when the flotation tank body 1 is inflated, the drug administration and water pumping operations can be performed simultaneously, and the amount of water pumped and the amount of drug pumped can be controlled to ensure the amount of foam generated in the flotation tank body 1 and prevent the occurrence of bubble overflow.

[0033] like Figure 1 As shown, a bubble forming plate 602 is installed at the bottom of the bubble duct 6, and a card slot 601 for inserting and connecting with the bubble forming plate 602 is opened at the bottom of the bubble duct 6.

[0034] Specifically, through this arrangement, sulfide ores containing different contents of gold and silver require bubbles of different densities for frothing operations, and the bubble duct 6 is replaced with bubble forming plates 602 of different densities, which can improve the frothing effect of the bubble duct 6.
