Strong magnets refer to magnets that have a significant advantage in terms of 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 holds great economic value.

The recovery of strong magnets mainly 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 good approach. For the extraction of rare metals, various techniques are available, such as roasting, leaching, and electrochemical methods.

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