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

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

Strong magnets have a wide range of applications across various fields. Recycling rare metals from strong magnets can reduce dependence on raw materials, enhance resource utilization, and also offers significant economic value. Therefore, the application and recycling of strong magnets are quite important.
