Abstract

The process (1) for the recovery of raw material from waste products comprises at least the phases of: supply (A) of one skein to be treated (3) composed of a harmonic steel fraction and a non-ferrous fraction; pre-treatment (F) of the skein to be treated (3) to separate the harmonic steel fraction from the non-ferrous fraction to obtain one treated skein (3b), comprising one step of mechanical separation (F1) of the harmonic steel fraction from the non-ferrous fraction; heat treatment (B) of the pre-treated skein (3 a) to obtain one treated skein (3b), the phase of heat treatment (B) comprising a step of inductive exposure (B1) of the pre-treated skein (3a) to one time-varying magnetic field, the step of inductive exposure (B1) being adapted to raise the temperature of the pre-treated skein (3 a) to one working temperature below 800° C.; post-treatment (E) of the treated skein (3b).
