Customer ServiceThe 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.
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.
Typically, the recycling technologies for the recovery of lead from spent lead paste can be based on both hydrometallurgical and pyrometallurgical processes. Recycling through hydrometallurgy basically consists of the acid or base leaching of scrap to put the metals in a solution [ 2, 4 ].
Additionally, the treatment of wastewater containing ammonia and nitrogen may limit the application range of these alkaline leaching processes. Lead-acid batteries dominate lead usage, accounting for about 80%. As secondary lead resources grow, recycling spent lead paste becomes crucial.
The lead in paste was recovered via hydrometallurgical leaching and electrowinning in chloride solution. The leaching ratio of lead was >99% under optimum conditions: temperature of 90 °C, CaCl 2 concentration of 400 g/L, Fe 2+ concentration of 5 g/L, pH 1.0, and leaching time of 2 h.
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.
