Strong magnets refer to magnets that have 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, the separation of strong magnets, followed by the extraction of rare metals from them. Methods for separating strong magnets include mechanical separation, manual disassembly, and automated disassembly, with automated disassembly being a good approach. For extracting rare metals, various techniques are available, such as oxidation roasting, leaching, and electrochemical methods.

Strong magnets have a broad range of applications across various 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.
