Description

Technical Field

[0001] The invention belongs to the technical field of aqua regia slag reduction, and in particular relates to a high-rhodium aqua regia slag reduction and recovery device. Background Art

[0002] Aqua regia residue is the insoluble material left after dissolving the platinum mesh using conventional dissolution methods. Its main component is rhodium. Due to its excellent resistance to acid and alkali corrosion, oxidation and other properties, rhodium is difficult to be effectively dissolved by conventional dissolution methods. Therefore, a certain amount of metallic rhodium will still remain in the aqua regia residue. In order to reduce costs, it is usually necessary to extract metallic rhodium from the aqua regia residue.

[0003] The existing method of extracting rhodium is mostly hydrogen reduction. Before hydrogen reduction, the aqua regia slag needs to be crushed, ground to a certain mesh size, and then flattened into a quartz boat, which is then placed in a tubular furnace for hydrogen reduction. The current problem is that due to the simple grinding method and the lack of effective weighing of the aqua regia slag, the aqua regia slag cannot be fully extracted during the subsequent hydrogen reduction process; and due to the specific shape characteristics of the quartz boat, it is still necessary to manually flatten and then load the aqua regia slag into the quartz boat. This process consumes a lot of manpower and time, and is inefficient. Summary of the invention
