Strong magnets refer to magnets with a significant advantage in magnetic field strength. They are widely used in various fields, including scientific research, electronics, energy, and environmental protection. Moreover, due to the presence of rare metals in strong magnets, their recycling also holds high economic value.

The recovery of strong magnets primarily involves two steps: first, separating the strong magnets, followed by extracting the rare metals from them. Methods for separating strong magnets include mechanical separation, manual disassembly, and automatic disassembly, with the latter being a favorable approach. For extracting rare metals, various techniques are available, such as oxidation roasting, leaching, and electrochemical methods.

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