3. Different recycling routes and/or technologies

3.1 Pyrometallurgical processes

Metallurgical processes have been optimized from the point of view of the technologies employed and the management of the polluting waste generated by this recycling method . Recycling metals by pyrometallurgy involves a succession of stages. First, the WEEE undergoes a pre-treatment and mechanical dismantling stage (figure 8 ). A shredding stage then reduces the size of the waste to be...
