Abstract
A method for recovering materials, in particular rejects or scraps of sheathed cables or wires, comprises introducing the parts into an enclosed space and placing them on a support provided with a drain, removing the oxygen from the enclosed space, raising the temperature inside the enclosed spaced until it reaches a melting temperature of one of the materials so that it drains through the drain, collecting the melted material in a recovery tank maintained at a temperature less than or equal to the melting temperature, then raising the temperature inside the enclosed space to cause the material remaining on the parts to dissipate in the form of vapour or gas, and recovering after cooling, the material drained into the recovery tank and the material or materials remaining on the support.
