Usually, 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.
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.
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.
The lead in the raw material was recovered via a direct leaching–electrowinning process in calcium chloride solution. Different from the traditional hydrometallurgical processes used to treat the lead paste, this new process does not require the desulphurisation step.
The leaching of lead was over 99% and the current efficiency was 96.3%. The energy consumption of the electrowinning was only 85.9 kWh/t Pb. The spent electrolyte was recyclable and the chlorine evolution was avoided. No desulfurization step is required in the novel process. Recycling spent lead-acid batteries has always been a research hotspot.
