Abstract

The possibility to recover metals from electric cables has been investigated in this work. Electric cables are usually constituted by various components, different for chemical-physical attributes, that is: i) conductors (i.e. copper or aluminum), ii) shield materials, usually metallic, iii) insulating materials (i.e. PVC, PE, rubber) and iv) coating materials (i.e plastic or metals). The study was particularly addressed to verify the effect of the comminution of such products when performed at different temperatures, ranging from room up to criogenic conditions, utilizing different cooling media as CO2 (-20°C) and nitrogen (-100°C). More specifically the parameters investigated have been particles morphological and morphometrical attributes and their degree of liberation, being these parameters of primarily importance in respect of the further electrostatic separation processes (particle surface charge and flow modalities) and final reuse (mixture properties).
