Non-Ferrous metals do not contain iron or iron alloys. Depending on their density, they can be classified as:
The limited availability of mineral reserves, the high extraction and processing costs, as well as the high value of Fe and Non-Fe metal, have urged company in investing money into machineries for separate collection and recovery.
One of the most efficient and popular ways to separate and recover Non-Fe metals is by making use of a physical principle: the eddy currents (also called Foucault’s currents).
Indeed, the Non-Ferrous materials are separated by the metallics thanks to a repelling force induced by the eddy current.
