ABSTRACT:
The raw material contains 80% by weight of an alloy of two at least of the metals of the group Fe, Ni, Cr, Cu, Co (and possibly sulphur), in the form of ingots, scrap-metal or mats, in pieces less than 200 mm in size. The alloys are firstly subjected to a chlorination operation at a temperature comprised between 600.degree.C and 1350.degree.C and then to the recovery operation for the chlorides formed. An enclosure, called a chlorination enclosure, is charged with (a) the alloy, (b) a gaseous mixture containing chlorine and HCl, (c) oxygen, and (d) at least one agent for regulating the temperature of the enclosure. The composition of the gaseous mixture, when it is constituted at the same time of Cl.sub.2 and of HCl, responds to the following conditions:
