Description

Technical Field

[0001] This invention relates to the field of gallium ore exploration equipment, specifically a method for exploring gallium ore in coal-bearing rock formations. Background Technology

[0002] Coal and rock mines contain a large amount of fly ash. In addition to elements such as aluminum and silicon, fly ash also contains abundant rare metal elements such as lithium, rubidium, and gallium. By extracting and utilizing these rare metals, fly ash can be used to achieve high added value. Gallium ore exploration can be completed by extracting gallium from fly ash.

[0003] According to the patent document with publication number CN116377225B, a method and intelligent equipment for recycling fly ash are disclosed. The method includes (1) providing a roasting activation product of fly ash; (2) acid leaching the roasting activation product to obtain an acid leaching solution; (3) passing the acid leaching solution through a first ion exchange resin for adsorbing Ga and Fe to obtain an exchange solution rich in Al and Li; and (4) removing Ca from the exchange solution rich in Al and Li and adjusting the pH value of the Ca removal solution. When this technical solution is used, the extraction, separation and enrichment of multiple strategic metals in fly ash are synergistically integrated into one process, which can maximize the comprehensive utilization of metal resources in fly ash and achieve fine deep processing, including improving the recovery rate and purity of various metal extractions. However, although this technical solution improves the extraction of metals, it cannot quickly compress the internal material space during processing and cannot quickly roast the material, which is inconvenient when using it.

[0009] Step 4: After removing gallium from the aluminum- and lithium-rich exchange solution, adjust the pH of the gallium-removing solution to obtain an aluminum-rich residue and a lithium-rich solution.

[0010] Step 5: Elute the ion exchange resin that has adsorbed gallium and iron obtained in Step 3 to obtain an eluent rich in gallium and iron, and remove iron from the eluent rich in gallium and iron using a second ion exchange resin to obtain a gallium-rich liquid.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Please see Figures 1 to 6 This invention provides a technical solution: a method for exploring gallium deposits in coal-bearing strata, comprising the following steps:

[0035] Step 1: Provide the calcination activation product of fly ash;

[0036] Step 2: The roasted and activated product is subjected to acid leaching to obtain an acid leaching solution;

[0037] Step 3: Pass the acid leaching solution through a first ion exchange resin used to adsorb gallium and iron to obtain an exchange solution rich in aluminum and lithium;

[0038] Step 4: After removing gallium from the aluminum- and lithium-rich exchange solution, adjust the pH of the gallium-removing solution to obtain an aluminum-rich residue and a lithium-rich solution.

[0039] Step 5: Elute the ion exchange resin that has adsorbed gallium and iron obtained in Step 3 to obtain an eluent rich in gallium and iron, and remove iron from the eluent rich in gallium and iron using a second ion exchange resin to obtain a gallium-rich liquid.

[0040] Step 6: After obtaining the gallium liquid, investigate the content of the liquid;

[0041] The roasting in step one is achieved by the roasting device body, which includes a fixed base 1, a fixed box 2 fixed to the top of the fixed base 1, a movable box 3 movably installed inside the fixed box 2, a support base 4 fixed to the top of the movable box 3, a feeding box 5 fixed to the top of the support base 4, a lifting mechanism 7 fixed to the top of the feeding box 5, a feeding pipe 6 installed on the side of the lifting mechanism 7, and one end of the feeding pipe 6 fixed to the feeding box 5. The lifting mechanism 7 is an electric push rod, which pushes the sealing plate 14 into the feeding port 13. The sealing plate 14 seals the feeding port 13 while cleaning the inner wall of the feeding port 13.

[0042] In this embodiment, a discharge assembly 9 is fixedly installed on the side of the fixed base 1. The discharge assembly 9 includes a discharge box 10. A connecting box 11 is movably installed inside the discharge box 10. An exhaust fan 12 is fixedly installed inside the connecting box 11. A roasting box 15 is fixed on the inner wall of the support base 4. A feed inlet 13 is opened between the roasting box 15 and the feeding box 5. A sealing plate 14 is movably installed inside the feed inlet 13. The sealing plate 14 is fixedly installed at one end of the lifting mechanism 7. A heating chamber 16 is opened inside the roasting box 15. A heating mechanism 17 is fixedly installed on the inner wall of the heating chamber 16. A support assembly 20 is movably installed inside the roasting box 15. A cavity 18 is opened inside the fixed base 1. The heating mechanism 17 is composed of electric heating wires. When the electric heating wires are energized, they generate high temperature to roast the internal materials. At the same time, the materials are stirred and mixed.

[0043] In this embodiment, the support assembly 20 is movably installed inside the cavity 18. A discharge port 19 is opened on the inner wall of the cavity 18, and one end of the discharge port 19 is connected to one end of the discharge box 10. The support assembly 20 includes a fixed plate 21. A power mechanism 22 is fixedly installed at the bottom of the fixed plate 21. An output shaft 23 is installed on the power mechanism 22. The power mechanism 22 is a brushless motor. The brushless motor drives the movable rod 24 to rotate on the fixed plate 21. The rotation cleans the surface of the filter assembly 25 on the fixed plate 21 while simultaneously mixing the materials. One end of the output shaft 23 is installed on the top of the fixed plate 21. The movable rod 24 is installed on the output shaft 23. The filter assembly 25 is fixedly installed on the fixed plate 21, and the filter assembly 25 is in contact with the bottom of the movable rod 24. A movable plate 26 is movably installed at the bottom of the fixed plate 21. The filter assembly 25 is a filter plate, which filters and classifies the materials.

[0044] In this embodiment, a lifting mechanism 27 is installed at the bottom of the movable plate 26. The lifting mechanism 27 is installed at the bottom of the cavity 18. An opening 28 is formed on the movable plate 26. A positioning mechanism 29 is movably installed inside the opening 28. Both the positioning mechanism 29 and the lifting mechanism 27 are electric push rods. The electric push rods push the fixed plate 21 and the movable plate 26 to move up and down. The up and down movement of the movable plate 26 controls the usage state of the filter assembly 25. One end of the positioning mechanism 29 is fixed to the bottom of the fixed plate 21. The positioning mechanism 29 is fixedly installed at the bottom of the cavity 18. An opening 30 is formed on the fixed plate 21. The opening 30 cooperates with the power mechanism 22. A sealing ring is fixed on the inner wall of the roasting box 15. The sealing ring cooperates with the fixed plate 21. A pushing mechanism 8 is fixedly installed between the fixed seat 1 and the support seat 4. The pushing mechanism 8 is an electric push rod. The electric push rod pushes the support seat 4 to move up and down. The up and down movement of the support seat 4 drives the movable box 3 to move up and down inside the fixed box 2.

[0045] This device receives its internal electrical components from an external power source. When using the device, the lifting mechanism 7 first moves the sealing plate 14 to the top of the feed box 5, allowing fly ash to enter the feed inlet 13 through the feed pipe 6. The fly ash initially comes into contact with sodium carbonate. Then, the lifting mechanism 7 is activated to push the sealing plate 14 downwards into the feed inlet 13. As the sealing plate 14 descends, it both blocks and seals the feed inlet 13 and, as it moves, also... The material on the inner wall of the heating chamber 13 is pushed downwards. After entering the interior of the roasting chamber 15, the material falls onto the fixed plate 21. The heating mechanism 17 on the inner wall of the heating chamber 16 is activated, generating high temperature to heat the material. While the material is being heated, the power mechanism 22 is activated to rotate the movable rod 24. The movable rod 24 drives the mixing of the materials, and roasting is completed simultaneously with the mixing. When a second addition of calcium carbonate is required for roasting, the sealing plate 14 is moved upwards, and the feed port 13 is opened to add the required calcium carbonate. After the initial roasting is completed, the pushing mechanism 8 is activated to the bottom support. The support 4 descends, causing the roasting chamber 15 to move downwards. As the roasting chamber 15 moves downwards, the fixed plate 21 remains stationary. The descent of the roasting chamber 15 creates space between the fixed plate 21 and the heating chamber 16, compressing the internal material. The compressed material remains on the fixed plate 21. When material sieving is required, the lifting mechanism 27 is activated to lower the movable plate 26. After the movable plate 26 descends, the bottom of the filter assembly 25 opens, and the power mechanism 22 is activated to cause the material to tumble inside the heating chamber 16. Simultaneously, the material flows through the filter assembly 25. The material falls to the inside of cavity 18 at the bottom, and the exhaust fan 12 is activated to generate suction. The suction forces the material inside cavity 18 out through discharge port 19 and collects it. When it is necessary to discharge the material on the fixed plate 21, the positioning mechanism 29 is activated to drive the fixed plate 21 to descend. After the fixed plate 21 descends, a gap is created between it and the bottom of the roasting box 15. The movable rod 24 is activated to rotate and the exhaust fan 12 is activated at the same time. The movable rod 24 pushes the material on the fixed plate 21 toward the discharge port 19, which helps the exhaust fan 12 to suck in the material, thus facilitating the complete discharge of the material later.
