[0002] The process of electrolytic gold recovery from precious metal-containing liquids may cause the electrolytically deposited gold to not adhere well to the cathode due to the presence of flotation agents, frothers, etc. in the liquid phase. Alternatively, the fine gold powder formed during the electrolysis process will flow out of the electrolytic cell in the form of "floating gold" along with the electrolytic lean liquid under water disturbance, resulting in a certain amount of gold loss. Therefore, it is necessary to effectively recover the floating gold and improve the electrolytic recovery rate.

[0036] Example 1

[0037] See also Figures 1 to 2 As shown, Example 1 of the utility model provides a device for intercepting gold loss caused by bleaching in a vertical precious metal electrolytic cell, which is installed as a whole inside the vertical precious metal electrolytic cell and arranged between the inner electrolytic cell 1 and the outer electrolytic cell, and includes a first-level high-temperature resistant synthetic fiber filtration interception and liquid distribution system, a second-level high-temperature resistant synthetic fiber filtration interception system, and a filter cell support system.

[0038] Among them, the first-level high-temperature resistant synthetic fiber filtering, intercepting and liquid distribution system is arranged below the inner tank liquid outlet 6, and is used for the first-level filtration of the electrolytic lean liquid containing "bleaching gold".

[0039] The secondary high-temperature resistant synthetic fiber filtration and interception system is staggered and connected to the primary high-temperature resistant synthetic fiber filtration and interception and liquid distribution system and has a staggered height difference, and is used to perform a second-stage filtration on the electrolytic lean liquid containing "bleached gold" after the first-stage filtration.

[0040] The filter tank support system is arranged between the inner electrolytic tank 1 and the outer electrolytic tank, and is used to movably support the first-level high-temperature resistant synthetic fiber filtering and intercepting liquid distribution system and the second-level high-temperature resistant synthetic fiber filtering and intercepting system.

[0041] In some embodiments, the first-level high-temperature resistant synthetic fiber filtration interception and liquid distribution system includes a first-level distribution filter tank 8 and a liquid guide tank 7; the first-level high-temperature resistant synthetic fiber filtration interception and liquid distribution system and the second-level high-temperature resistant synthetic fiber filtration interception system are staggered and connected through the liquid guide tank 7.

[0042] The side of the first-level distribution filter tank 8 is provided with several groups of liquid outlets with a horizontal height lower than the filter cross-section; the top of the liquid guide tank 7 is connected to the liquid guide outlet, and the bottom is connected to the top water inlet of the second-level high-temperature resistant synthetic fiber filter interception system.

[0043] The first-level distribution filter tank 8 is installed below the inner tank liquid outlet 6, and filtrate discharge holes 11 are provided on the bottom and side surfaces thereof, and an elastic high-temperature resistant synthetic fiber filter cotton filler layer 12 is laid inside.

[0044] In some embodiments, the primary distribution filter 8 performs the first-stage interception of the "gold bleaching" lean liquid, which is then discharged into the lower portion of the pressure housing through the bottom filtrate discharge hole 11. Due to the limited interception area of the primary distribution filter 8, the "gold bleaching" electrolytic lean liquid is not intercepted in time. Instead, it is diverted into two liquid guide slots 7 through the horizontal outlets provided on both sides of the primary distribution filter 8 and at the bottom of the water flow section for secondary filtration and interception.

[0045] The secondary high-temperature resistant synthetic fiber filtering and intercepting system includes several groups of secondary filter tanks 10.

[0046] The secondary filter tank 10 has filtrate discharge holes 11 on the bottom and sides, and a high-temperature resistant synthetic fiber filter cotton filler layer 12 is laid inside. The difference from the primary distribution filter tank 8 is that the secondary filter tank 10 has no liquid outlet on both sides, and the upper edges of the sides are horizontal.

[0047] The filtrate discharge holes 11 should be arranged with the maximum drainage area while meeting the processing technology requirements; the aperture of the filtrate discharge holes 11 is larger than the filter particle size of the high-temperature resistant synthetic fiber filter cotton filler layer 12.

[0048] The "bleached gold" accumulated in the first-level distribution filter tank 8 and the second-level filter tank 10 is taken out together with the gold mud, and the gold is recovered after washing with water, and the high-temperature resistant synthetic fiber filter cotton filling layer 12 is reused and can be used repeatedly.

[0049] The filter tank support system includes a filter tank bracket 9 and an inner tank reinforcement frame 2 for movably supporting the first-level high-temperature resistant synthetic fiber filtering and intercepting liquid distribution system and the second-level high-temperature resistant synthetic fiber filtering and intercepting system.

[0050] The first-level high-temperature resistant synthetic fiber filtering, intercepting and liquid distribution system is movably installed on the outer wall of the electrolytic inner tank 1 through the filter tank bracket 9; the second-level high-temperature resistant synthetic fiber filtering, intercepting and liquid distribution system is symmetrically installed on the outer wall of the electrolytic inner tank 1 adjacent to the first-level high-temperature resistant synthetic fiber filtering, intercepting and liquid distribution system through the inner tank reinforcement frame 2.

[0051] The working process of the device for intercepting gold loss in a vertical precious metal electrolytic cell provided by the utility model is as follows:

[0052] The precious metal-containing liquid enters the electrolytic inner tank 1 through the liquid inlet 3 for electrolytic gold deposition. During the process of electrolytic gold recovery from the precious metal-containing liquid, the electrolytically deposited gold may not adhere well to the cathode due to the presence of flotation agents, foaming agents, etc. in the liquid phase, or the fine gold powder formed during the electrolysis process may flow out of the electrolytic tank in the form of "bleached gold" along with the electrolytic lean liquid under the disturbance of the water flow. Therefore, a first-level high-temperature resistant synthetic fiber filtration interception and liquid distribution system is installed below the inner tank liquid outlet 6 of the vertical electrolytic inner tank 1 through several filter tank brackets 9. When the electrolytic lean liquid containing "bleached gold" passes through the first-level distribution filter tank 8, it is intercepted by the high-temperature resistant synthetic fiber filter cotton packing layer 12, and the clear liquid enters the lower part of the vertical pressure electrolytic outer tank through the filtrate discharge holes 11 set at the bottom and side, realizing the first-level filtration.

[0053] The electrolytic lean liquid containing "bleached gold" that was not filtered in time during the first stage of filtration is evenly distributed into the two liquid guide grooves 7 through the liquid outlets opened on the two sides of the first-level distribution filter tank 8, and then enters the secondary filter tanks 10 of the two secondary high-temperature resistant synthetic fiber filtration and interception systems. The electrolytic lean liquid containing "bleached gold" that was not filtered in time during the first stage of filtration passes through the high-temperature resistant synthetic fiber filter cotton filler layer 12. After the second stage of filtration, the clean lean liquid is also discharged into the lower part of the vertical pressure electrolytic outer tank through the filtrate discharge holes 11 set at the bottom and sides, thereby achieving complete interception of the "bleached gold".

[0054] The "bleached gold" accumulated in the first-level distribution filter tank 8 and the second-level filter tank 10 is taken out together with the gold mud, and the gold is recovered after washing with water. The high-temperature resistant synthetic fiber filter cotton filling layer 12 is reused and can be used repeatedly. When it needs to be finally disposed of, the gold is recovered after ashing.
