WebbPyrometallurgy is the predominantly used technology for industrial e-waste treatment. In industrial pyrometallurgical processes for e-waste recycling, the scrap is usually fed into furnaces, where the load is smelted via flash or bath smelting. Subsequently, the conversion process takes place (Zhang and Xu, 2016 ).
