In a waste treatment plant dealing with municipal waste, glass, WEEE, post-combustion slag, etc. one of the first operations carried out is the extraction and recovery of ferromagnetic metal.
This happens because:
The separation of ferrous metal happens thanks to the principle of magnetic attraction: the magnetic field generated by permanent or electrical magnets attracts the ferromagnetic intrusions, extracting them from the waste flow.
There are different types of magnetic separators that can be installed in a waste treatment plant depending on the quantity and size of the ferrous metal to be extracted.
