Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.
The recovery of lead from spent lead acid battery paste (SLP) is not only related to the sustainable development of the lead industry, but also to the sustainable evolution environment.
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.
The recycling of waste lead paste is primarily focused on using Pb metal as the final product and returning it to the industrial chain of Pb as the lead ingot. More than 80% of refined lead consumption worldwide is concentrated in the lead–acid storage battery industry.
There are four main components in spent lead acid battery: polymeric containers, lead alloy grids, waste acids and pastes. Among them, the pastes mainly comprise lead oxide (∼9%), lead dioxide (∼28%), lead sulfate (∼60%) and a small amount of lead (∼3%) (Zhu et al., 2012a).
