All metals can be recycled with excellent results. Also in terms of energy recovery, because let's not forget that producing a pure metal from the mineral is a highly energy-intensive production cycle. Re-melting metals is also a way to limit CO2 emissions, as well as avoiding opening other mines in the world and saving a lot on disposal.
The most commonly recycled materials include in addition to of course gold, silver and platinum, and then iron, steel, copper, brass, aluminum, nickel, palladio, cobalt and various other ferrous and metallic alloys, in addition to the so-called "rare earths", chemical elements indispensable in the most modern technologies, including scandium, ittrio, neodymium, europe, gadolinium, cerio, lantanio, disprosio e lutezio. Correct disposal of scrap must take place by carefully separating the metal pieces: ad esempio, thanks to the use of powerful magnets, ferrous metals such as steel are separated, while for metals such as aluminum separation is possible thanks to the use of electronic currents. All this in order to enhance each material and transform it back into a raw material suitable for any use.
