High-magnetism refers to magnets with a significant advantage in magnetic field intensity. They are widely used in various fields, including scientific research, electronics, energy, and environmental protection. Moreover, due to the rare metals contained in high-magnetism magnets, recycling them holds great economic value.

The recovery of strong magnets primarily involves two steps: first, separating the strong magnets, followed by extracting the rare metals from them. The methods for separating strong magnets include mechanical separation, manual disassembly, and automatic disassembly, among others. Automatic disassembly is an effective method. In the process of extracting rare metals, various techniques are available, such as oxidation roasting, leaching, and electrochemical methods.

The applications of strong magnets are vast, spanning multiple fields. Recycling rare metals from strong magnets can reduce dependence on raw materials, enhance resource utilization, and also holds significant economic value. Therefore, the application and recycling of strong magnets are quite important.
