3.2.4. Vacuum roasting (Wang et al., 2022) successfully recovered lead and sulfur from spent lead-acid batteries using a vacuum roasting route. For lead recovery, the process involved several steps. First, the battery was crushed, and the lead paste obtained was uniformly mixed with Na 2 CO 3 in a ball milling process at a ratio of 4:1.
