Pyrometallurgical method. 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 ...
Abstract. Electrometallurgy is an important branch of metallurgy which uses electrical energy in winning of metals from leach liquors and refining of crude metals obtained via the pyrometallurgical route (e.g., blister copper and lead bullion) as well as by hydrometallurgical and electrometallurgical routes (e.g., aluminum).
