Description

Technical Field

[0001] The present invention relates to the technical field of aluminum slag sorting, and in particular to a sorting device for treating electrolytic aluminum waste slag. Background Art

[0002] Aluminum electrolytic slag is one of the inevitable byproducts of the aluminum electrolysis industry. It is produced during the electrolytic smelting of aluminum. In this process, bauxite is decomposed into aluminum metal and oxygen through a high-temperature electrolytic reaction. In order to extract pure aluminum metal, it is usually necessary to electrolyze it in a mixture of aluminum fluoride and other fluoride salts through an electrolytic cell. Although this process successfully separates aluminum from bauxite, it produces a large amount of slag.

[0003] Electrolytic aluminum waste slag generally includes the following components: Unreacted bauxite: Bauxite does not react completely during the electrolysis process and remains in the waste slag. This unreacted bauxite needs further processing to extract the aluminum content.

[0004] Fluoride salts in the electrolytic cell: During the electrolysis process, aluminum fluoride is a necessary molten salt, and fluoride salts may also be mixed with other electrolysis by-products such as sodium fluoride, calcium fluoride, etc. Due to the presence of fluoride salts, these waste residues contain a certain amount of fluoride, which may cause serious pollution to the environment if not treated.

[0005] Impurities generated during electrolysis: During the electrolysis of aluminum, some oxides, carbon slag and other metal impurities (such as iron, calcium, magnesium, etc.) will accumulate on the surface of metallic aluminum. These impurities are usually mixed with bauxite or fluoride salts to form waste slag.

[0006] Residues from incomplete alumina reaction: The electrolytic reaction of alumina cannot be 100% efficient, so a certain amount of incompletely reacted bauxite or alumina components is produced.

[0007] The composition of electrolytic aluminum waste slag is complex, and its main components are unreacted bauxite, fluoride salts, carbon slag and a small amount of metal impurities. The main problem of waste slag is that it contains a large amount of fluoride and unreacted bauxite components. If these components are directly discharged, it will not only cause environmental pollution, but also waste resources.

[0008] Environmental issues of electrolytic aluminum waste slag: Aluminum electrolytic waste contains a large amount of fluoride, which is very harmful to the environment and human health. Excessive fluoride can penetrate into the soil and water, seriously affecting the ecological environment, destroying soil quality, and endangering plant growth. Long-term exposure to fluoride may cause poisoning or even endanger life for humans and animals.

[0009] In addition, if the bauxite and some metal impurities contained in the electrolytic aluminum waste are not properly handled, it may also cause a waste of resources. Some bauxite in the waste slag still contains a certain amount of aluminum. Through recycling and treatment, the waste of raw materials can be reduced, which has a positive resource circulation significance for production.

[0010] Treatment method of electrolytic aluminum waste slag: The current treatment methods for fluoride, bauxite, metal impurities and other components in electrolytic aluminum waste slag mainly include the following: 1. Sorting and recycling Since the electrolytic aluminum waste slag contains a large amount of unreacted bauxite and some recyclable metal components, it is first necessary to use sorting equipment to separate the bauxite, metal impurities and other useful components in the waste slag. Commonly used sorting methods are: Magnetic separation: The ferromagnetic metal part of the waste slag is separated by magnetic force. Metal impurities such as iron, calcium, and magnesium in the waste slag can be separated by magnetic separation, flotation, and other means.

[0011] Gravity separation: Utilizing the different densities of waste slag particles, gravity separation equipment (such as shaking tables, spiral separators, etc.) is used to separate the heavier metal components and lighter bauxite in the waste slag.

[0012] Flotation separation: The bauxite in the waste slag is separated by flotation. The difference in buoyancy of different minerals is used to separate the useful aluminum ore from other impurities, and then the aluminum is recovered.

[0013] High temperature roasting: By heating the waste slag to a higher temperature, some components undergo chemical reactions, removing fluoride salts and other impurities to obtain purer bauxite or aluminum metal.

[0014] Through these treatment methods, useful components in the waste residue can be recovered, which not only reduces environmental pollution but also reduces the demand for raw materials.

[0015] 2. Fluoride treatment Aluminum electrolytic waste slag contains a large amount of fluoride, so a key point in its treatment is how to safely and effectively remove the fluoride. Common fluoride treatment methods include: Acid washing method: Use an acid solution (such as dilute sulfuric acid) to soak the waste residue to dissolve the fluoride in it. Most of the fluoride in the waste residue can be removed by acid washing, but this method requires attention to the recovery and treatment of waste acid to avoid polluting water sources.

[0016] Composting method: By mixing waste residue with organic matter such as straw and soil for composting, the fluoride concentration in the waste residue is reduced by biodegradation. This method is suitable for waste residue with relatively low fluoride concentration.

[0017] Solvent extraction method: Use special solvents to extract fluoride from waste residues. This method is highly efficient but relatively expensive and is suitable for large-scale industrial processing.

[0018] Solidification and landfill method: If the concentration of fluoride in the waste residue is high and difficult to remove, the fluoride in the waste residue can be stabilized by solidification and landfill to prevent it from seeping into groundwater or soil.

[0019] 3. Comprehensive utilization of waste residue In addition to recycling bauxite and metal components, aluminum electrolytic slag can also be used as a resource. For example, fluoride salts and bauxite in the slag can be used as part of building materials, especially in cement production, bauxite and fluoride salts can be used as flux.

[0020] In addition, the metal components such as calcium and magnesium contained in the electrolytic aluminum waste slag can also be used to produce other metal materials or fertilizers, which has certain economic value. In this way, waste slag can be turned into treasure and achieve the recycling of resources.

[0021] The treatment and sorting of electrolytic aluminum waste slag is a complex and challenging task, covering the removal of fluoride in the waste slag, the recovery of useful bauxite and metal components, and the resource utilization of the waste slag. Through efficient sorting and recycling technology, not only can the environmental pollution of waste slag be reduced, but also the resource utilization rate can be effectively improved. With the increasingly stringent environmental protection standards and the continuous development of technology, the treatment technology of electrolytic aluminum waste slag will become more mature, providing important support for the sustainable development of the aluminum industry.

[0022] The sorting equipment used for electrolytic aluminum waste slag treatment is a mechanical equipment specially used in the electrolytic aluminum waste slag treatment process. Its main function is to separate and sort the different components in the electrolytic aluminum waste slag, such as metal components, electrolyte components, carbonaceous materials and other impurities, according to the differences in their physical and chemical properties, so as to achieve the purpose of recovering valuable components, reducing the pollution of waste to the environment and improving the comprehensive utilization value of waste slag. However, the sorting equipment for electrolytic aluminum waste slag treatment uses the differences in physical and chemical properties to sort the waste slag. However, due to the complex composition of electrolytic aluminum waste slag, the property differences between some components are not obvious, resulting in incomplete separation, making the purification effect of the target metal element unsatisfactory. When the complexity of the waste slag composition exceeds the expected range of the equipment sieve hole, the performance of the sorting equipment will be greatly reduced, and the equipment needs to be adjusted or improved to adapt to the new type of waste slag. Summary of the invention
