Process for the recovery of raw material from waste products

1) Process (1) for the recovery of raw material from waste products, comprising at least the phases of:

• supply (A) of at least one skein to be treated (3) derived from waste products and composed of at least a harmonic steel fraction and a non-ferrous fraction;
• pre-treatment (F) of said skein to be treated (3) to separate said harmonic steel fraction from said non-ferrous fraction to obtain at least one treated skein (3b);
• heat treatment (B) of said pre-treated skein (3a) to obtain at least one treated skein (3b), said phase of heat treatment (B) comprising a step of inductive exposure (B1) of said pre-treated skein (3a) to at least one time-varying magnetic field for the induction of eddy electric currents in said pre-treated skein (3a), said step of inductive exposure (B1) being adapted to raise the temperature of said pre-treated skein (3a) to at least one working temperature;
• post-treatment (E) of said treated skein (3b) to obtain steel reusable as raw material;
• characterized by the fact that said working temperature is substantially below 800° C. and by the fact that said phase of pre-treatment (F) comprises at least one step of mechanical separation (F1) of said harmonic steel fraction from said non-ferrous fraction.
