As this process lacked effective environmental protection and posed a threat to human health, it was banned in China. Consequently, pyrometallurgy and pyrolysis were developed based on this thermal process (Quan et al., 2010). Pyrometallurgy is a traditional technology for recovery of non-ferrous metals as well as precious metals from waste PCBs.
