Description

Technical Field

[0001] The invention belongs to the technical field of production of antimony-containing gold concentrate, in particular to a production and refining device and process of antimony-containing gold concentrate. Background Art

[0002] In the on-site production process of antimony recovery, the main work content includes the steps of slurry adjustment, alkaline leaching, filter pressing and washing, electrolytic deposition, and antimony oxidation precipitation of antimony-containing gold concentrate. First, after slurry adjustment, the antimony-containing gold concentrate is alkaline leached with sodium sulfide and sodium hydroxide to dissolve the antimony element from the raw material. Then, a primary filtrate and filter cake are obtained through a filter pressing and washing. The primary filtrate is subjected to an electrolytic deposition process to produce a cathode antimony product, and the primary filter cake is further washed and filtered twice to obtain a secondary filtrate and a secondary filter cake (i.e., antimony tail). The secondary filtrate enters the antimony oxidation precipitation workshop for further treatment to recover the antimony element in the solution and finally obtain the sodium antimonate product.

[0003] Among them, the antimony-gold concentrate is transported to a closed stirring leaching tank after slurry adjustment, and the two agents are added for alkaline leaching. In the prior art, sodium sulfide and sodium hydroxide are added through a feeding port set at the top of the closed stirring leaching tank, and then a stirring device is used to ensure that the agents are fully mixed with the slurry. If the amount of agents added at one time is too large, the concentration of sodium sulfide and sodium hydroxide in local areas of the slurry will be too high, and the reaction speed will be too fast, causing the slurry to overflow, which will pose certain safety hazards.

[0004] To this end, the present invention provides a production and refining device and process for antimony-containing gold concentrate. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1: Figures 1 to 6 As shown, an antimony-containing gold concentrate production and refining device according to an embodiment of the present invention comprises a sealed stirring box 1, on which a feed pipe 2 and a discharge pipe 3 are arranged, and a reagent box 4 is fixedly installed on the top of the sealed stirring box 1;

[0035] The antimony-containing gold concentrate that has been slurried is fed into the sealed stirring box 1 through the feed pipe 2 , and the slurry after leaching can be discharged through the discharge pipe 3 .

[0036] The interior of the reagent box 4 is used to store sodium sulfide and sodium hydroxide.

[0037] A rotating rod 7 is rotatably installed inside the sealed stirring box 1, a sliding ring 26 is provided on the outer wall of the rotating rod 7, a stirring rod 20 is fixedly installed on the outer wall of the sliding ring 26, a stirring blade 17 is fixedly installed on the outer wall of the stirring rod 20, a plurality of stirring rods 20 are provided, and the plurality of stirring rods 20 are arranged in an annular shape on the outer wall of the sliding ring 26;

[0038] The rotating rod 7 can drive the sliding ring 26 to rotate inside the sealed stirring box 1. When the sliding ring 26 rotates, it will drive multiple stirring rods 20 to rotate at the same time. At this time, if the sodium sulfide and sodium hydroxide in the reagent box 4 are poured into the sealed stirring box 1, they can be quickly mixed with the slurry through multiple stirring rods 20, and alkaline leaching can be performed. The stirring blades 17 are arranged at the top and bottom of the stirring rods 20, which can effectively improve the efficiency of stirring the slurry.

[0039] A piston cylinder 11 is provided on the sealed mixing box 1, and a piston 22 is slidably installed inside the piston cylinder 11. A first connecting tube 18 and a second connecting tube 19 are provided on the piston cylinder 11. The other end of the first connecting tube 18 is connected to the inner cavity of the medicine box 4, and the other end of the second connecting tube 19 extends to the inside of the rotating rod 7. Both the first connecting tube 18 and the second connecting tube 19 are provided with a one-way valve.

[0040] The one-way valve provided on the first connecting tube 18 can effectively block the conduction direction of the piston cylinder 11 toward the first connecting tube 18 , and the one-way valve provided on the second connecting tube 19 can effectively block the conduction direction of the second connecting tube 19 toward the piston cylinder 11 .

[0041] When the piston 22 slides upward inside the piston cylinder 11, the sodium sulfide and sodium hydroxide in the medicine box 4 can be sucked into the piston cylinder 11 through the first connecting pipe 18, and then the piston 22 slides downward inside the piston cylinder 11, so that the sodium sulfide and sodium hydroxide sucked into the piston cylinder 11 can be transported to the rotating rod 7 through the second connecting pipe 19.

[0042] As a preferred embodiment of the present invention, a limiting groove is provided on the rotating rod 7, a limiting block is fixedly installed on the inner wall of the sliding ring 26 and extends to the inside of the limiting groove, a receiving groove is provided inside the rotating rod 7, a spiral tube 27 is provided inside the receiving groove, one end of the spiral tube 27 is connected to the second connecting tube 19, and the other end is connected to the sliding ring 26.

[0043] The limiting groove on the rotating rod 7 can effectively limit the rotation of the sliding ring 26. The limiting groove is vertically opened, so that the sliding ring 26 can slide along the inside of the limiting groove. When the sliding ring 26 slides upward inside the limiting groove, it will drive the stirring rod 20 and the stirring blade 17 to slide upward, and the same is true when sliding downward. Therefore, when the rotating rod 7 rotates, it will drive the sliding ring 26 to rotate. At this time, the sliding ring 26 will drive multiple stirring rods 20 and stirring blades 17 to rotate synchronously, stirring the slurry in the sealed stirring box 1 to facilitate the reaction with sodium sulfide and sodium hydroxide.

[0044] The spiral tube 27 is placed inside the receiving groove. The spiral tube 27 is stretched or contracted by force. The second connecting tube 19 is connected to the spiral tube 27, and the other end of the spiral tube 27 is connected to the sliding ring 26. Therefore, the sodium sulfide and sodium hydroxide in the piston cylinder 11 can be transported to the inside of the sliding ring 26 through the second connecting tube 19.

[0045] As a preferred embodiment of the present invention, the sliding ring 26 and the stirring rod 20 are both hollow, and the inner cavities are connected, and a discharge pipe 21 is fixedly installed on the stirring rod 20.

[0046] A cross-shaped diaphragm may be provided inside the discharge pipe 21 . The cross-shaped diaphragm is pushed open by air pressure, which can effectively reduce the slurry from entering the inside of the stirring rod 20 through the discharge pipe 21 .

[0047] When the piston 22 slides downward inside the piston cylinder 11, the sodium sulfide and sodium hydroxide sucked into the piston cylinder 11 can be transported to the spiral tube 27 through the second connecting pipe 19, then enter the inside of the sliding ring 26, and finally be discharged into the sealed stirring box 1 through the discharge pipe 21 provided on the stirring rod 20. The sodium sulfide and sodium hydroxide can push open the cross diaphragm valve due to the pressure given by the sliding of the piston 22. Through the cooperation of the piston 22 and the piston cylinder 11, the sodium sulfide and sodium hydroxide transported to the sealed stirring box 1 can be intermittent, which can effectively avoid the problem of excessive single dosage, excessive reaction speed, and slurry overflow.

[0048] As a preferred embodiment of the present invention, a driving motor 5 is fixedly installed on the top of the sealed mixing box 1, a first driving wheel 6 is fixedly installed on the output shaft of the driving motor 5, a first driven wheel 8 is fixedly installed on the outer wall of the rotating rod 7, and the first driving wheel 6 and the first driven wheel 8 are connected by a belt.

[0049] By starting the driving motor 5, the first driving wheel 6 can be driven to rotate, and the first driven wheel 8 can be driven to rotate under the action of the belt. When the first driven wheel 8 rotates, the rotating rod 7 will rotate, so that the sliding ring 26 drives the stirring rod 20 and the stirring blade 17 to rotate.

[0050] As a preferred embodiment of the present invention, a slide rod 12 is slidably installed inside the piston cylinder 11, one end of the slide rod 12 is fixedly connected to the piston 22, and the interior of the slide rod 12 is connected to a first reciprocating screw rod 23 via threads.

[0051] A limit rod is provided between the slide rod 12 and the piston cylinder 11 for limiting the sliding trajectory of the slide rod 12. When the first reciprocating screw 23 rotates, it will drive the slide rod 12 to slide back and forth up and down inside the piston cylinder 11, and will also drive the piston 22 to slide back and forth up and down inside the piston cylinder 11, and cooperate with the first connecting tube 18 and the second connecting tube 19 to transport the sodium sulfide and sodium hydroxide in the reagent box 4 to the inside of the sliding ring 26, and finally send them into the sealed mixing box 1 through the discharge pipe 21 on the stirring rod 20. Through the cooperation of the piston 22 and the piston cylinder 11, the sodium sulfide and sodium hydroxide transported to the sealed mixing box 1 can be intermittent, which can effectively solve the problem of excessive single dosage, too fast reaction speed, and slurry overflow.

[0052] As a preferred embodiment of the present invention, a driving gear 13 is fixedly mounted on the top of the first driven wheel 8 , a driven gear 14 is fixedly mounted on the top of the first reciprocating screw rod 23 , and the driving gear 13 is meshed with the driven gear 14 .

[0053] When the first driven wheel 8 rotates, it will drive the driving gear 13 to rotate. At this time, the driven gear 14 meshing with the driving gear 13 will rotate synchronously and control the first reciprocating screw 23 to rotate, so that the slide rod 12 drives the piston 22 to slide up and down inside the piston cylinder 11.

[0054] As a preferred embodiment of the present invention, the end of the stirring rod 20 away from the rotating rod 7 is fixedly connected to a fixing ring 16, the top of the fixing ring 16 abuts against an upper clamp 24, and the bottom of the fixing ring 16 abuts against a lower clamp 25, and a second reciprocating screw 15 is rotatably installed in the sealed stirring box 1, and the second reciprocating screw 15 passes through the upper clamp 24 and the lower clamp 25.

[0055] The plurality of stirring rods 20 are all fixedly connected to the fixing ring 16. When the sliding ring 26 drives the plurality of stirring rods 20 to rotate, the fixing ring 16 will also rotate synchronously. The outer wall of the fixing ring 16 does not fit the inner wall of the sealed stirring box 1. The second reciprocating screw rod 15 is located between the fixing ring 16 and the inner wall of the sealed stirring box 1. One end of the upper clamping piece 24 and the lower clamping piece 25 fit the inner wall of the sealed stirring box 1. Therefore, when the second reciprocating screw rod 15 rotates, the upper clamping piece 24 and the lower clamping piece 25 will move up or down synchronously. The clamping piece 25 clamps the fixed ring 16, so when the upper clamping piece 24 and the lower clamping piece 25 slide, the fixed ring 16 will be driven to slide. The sliding ring 26 and the stirring rod 20 are driven to slide by the fixed ring 16, which can effectively change the position where the discharge pipe 21 discharges sodium sulfide and sodium hydroxide. As the discharge position changes continuously inside the sealed stirring box 1, the sodium sulfide and sodium hydroxide can be better contacted and reacted with the slurry, effectively solving the problem of excessive concentration of sodium sulfide and sodium hydroxide in local areas of the slurry, thereby affecting the efficiency of alkaline leaching.

[0056] As a preferred embodiment of the present invention, a second driving wheel 9 is fixedly mounted on the rotating rod 7, one end of the second reciprocating screw rod 15 extends out of the top of the sealed mixing box 1, and a second driven wheel 10 is fixedly mounted, and the second driving wheel 9 and the second driven wheel 10 are connected by a belt.

[0057] When the rotating rod 7 rotates, the second driving wheel 9 can be driven to rotate, and under the action of the belt, the second driven wheel 10 can be driven to rotate, thereby realizing the control of the second reciprocating screw rod 15.

[0058] like Figure 7 As shown, a process for producing and refining antimony-containing gold concentrate, the process adopts the above-mentioned antimony-containing gold concentrate production and refining device, and includes the following steps:

[0059] S1: The antimony-containing gold concentrate is slurried and transported to the sealed stirring box 1 through the feed pipe 2, and the sodium sulfide and sodium hydroxide in the reagent box 4 are fed into the sealed stirring box 1 for alkaline leaching;

[0060] S2: The leached slurry is subjected to a first filter press to obtain a primary filtrate and a primary filter cake. The primary filtrate is finely filtered and then enters a liquid pool for electrolysis. The primary filter cake is then washed and filtered for a second time to obtain a secondary filtrate and a secondary filter cake.

[0061] S3: The secondary filtrate enters the oxidation and precipitation workshop, and after purification, it is oxidized and precipitated to further recover the antimony in the solution to obtain the sodium antimonate product. The secondary filtrate uses air as an oxidant and hydroquinone as a catalyst. At the same time, sodium hydroxide is added to oxidize and precipitate antimony. The oxidation time is controlled at 24h to oxidize the soluble sodium thioantimonite in the antimony electrodeposition lean solution into insoluble sodium antimonate.

[0062] Working principle: By starting the driving motor 5, the first driving wheel 6 can be driven to rotate, and under the action of the belt, the first driven wheel 8 can be driven to rotate. When the first driven wheel 8 rotates, it will drive the driving gear 13 to rotate. At this time, the driven gear 14 meshing with the driving gear 13 will rotate synchronously and control the rotation of the first reciprocating screw 23, so that the slide rod 12 drives the piston 22 to slide up and down inside the piston cylinder 11. The piston 22 slides upward inside the piston cylinder 11, and the first connecting pipe 18 sucks the sodium sulfide and sodium hydroxide in the reagent box 4 into the piston cylinder 11. The piston 22 is in The interior of the piston cylinder 11 slides downward, and the sodium sulfide and sodium hydroxide sucked into the piston cylinder 11 are transported to the spiral tube 27 through the second connecting tube 19, and then enter the interior of the sliding ring 26, and finally discharged into the interior of the sealed stirring box 1 through the discharge pipe 21 set on the stirring rod 20. The sodium sulfide and sodium hydroxide can push open the cross diaphragm valve through the pressure given by the sliding of the piston 22. Through the cooperation of the piston 22 and the piston cylinder 11, the sodium sulfide and sodium hydroxide transported to the sealed stirring box 1 can be intermittent, which can effectively avoid the problem of excessive single dosage, excessive reaction speed, and slurry overflow.

[0063] By starting the driving motor 5, the first driving wheel 6 can be driven to rotate, and the first driven wheel 8 can be driven to rotate under the action of the belt. At this time, the rotating rod 7 can drive the second driving wheel 9 to rotate. Under the action of the belt, the second driven wheel 10 can drive the second reciprocating screw 15 to rotate, so that the upper clamping piece 24 and the lower clamping piece 25 drive the fixed ring 16 to move up or down. The sliding ring 26 and the stirring rod 20 are driven to slide by the fixed ring 16, which can effectively change the position of the discharge pipe 21 to discharge sodium sulfide and sodium hydroxide. As the discharge position changes continuously inside the sealed stirring box 1, the sodium sulfide and sodium hydroxide can be better contacted and reacted with the slurry, effectively solving the problem of excessive concentration of sodium sulfide and sodium hydroxide in local areas of the slurry, thereby affecting the efficiency of alkaline leaching.
