Scrap metal recycling is the process of reusing old metal to make new products. In doing so, you get to save the environment and also create job opportunities. The process involves identifying metals, recovering them, and refining them before reclaiming them.
For identification, a magnet is required to separate the ferrous metal from the non-ferrous. Ferrous metal is made up of iron, while non-ferrous does not have traces of iron. However, further tests still have to be conducted to determine what can be recycled and which ones to throw away.
