Pyrometallurgical Process
Pyrometallurgical process is one that involves a high temperature (above 1200 °C) smelting process to break down and treat spent battery materials (Fig. 1 A) (Georgi-Maschler et al., 2012).Essentially, spent LIBs are burnt in a furnace without any kind of pretreatment steps. Their components are broken down into subcomponents while …
