Solution Preview

There are basically three types of permanent magets: alnicos, ceramics, and rare earth. All types of permanent magnets be rendered safe for disposal through heating, which removes their magnetic properties. However the most difficult to dispose of are the rare earth magnets. Rare earth magnets are powerful and will accelerate quickly toward each other and metal objects. A person can be injured by these high speeds if precautions are not taken. Because of these precautions, it is expensive to recycle them. However rare earth elements are becoming scarce and it is becoming cost effective to recycle them nonetheless.

The recycling of magnets is generally done as part of e-waste recycling programs. This is because rare earth magnets are important components of hard drives and cell phones. E-waste programs are ...
