How to Separate Precious Metal |
A wide variety of different types of electronics and other objects contain at least one type of precious metal. In many cases, the trace amounts of these metals are fused together inside of the object. In order to recover those metals once the object has worn out or broken, you'll need to properly know how to separate the metal.
