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 …

Extraction of Copper: Detailed Process
Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.
