Free QuoteUsually, spent lead-acid batteries are separated in lead recycling plants by dismantling and sorting into four fractions: lead paste, metallic fragments, waste acid, and plastic case (Worrell and Reuter, 2014; Zhang et al., 2019). The processing of lead paste is relatively complex because it contains refractory lead sulphate.
Lead acid battery (LAB) recycling benefits from a long history and a well-developed processing network across most continents. Yet, LAB recycling is subject to continuous optimization efforts because of increasingly stringent regulations on process discharge and emissions.

Lead, PbSO 4, or other lead products are extracted from the bottom of the electrolyzer under forced stirring and current. The spent electrolyte could be further purified as pure electrolyte, which could then be reused in the production of LABs.
Recycling spent lead-acid batteries has always been a research hotspot. Although traditional pyrometallurgical smelting is still the dominant process, it has serious environmental drawbacks, such as the emission of lead dust and SO 2, and high energy consumption. This study presents a clean process for recycling spent lead-acid battery paste.
The material is processed via reductive leaching using calcium chloride and ferrous ions to extract the lead from lead paste. The lead in the leaching liquor can be recovered as metallic lead powder via electrowinning using soluble anode (iron sheet).
