Lead-acid batteries dominate lead usage, accounting for about 80%. As secondary lead resources grow, recycling spent lead paste becomes crucial. Disassembled batteries yield four main components: spent lead paste, polymeric containers, lead grids, and waste acid, with spent lead paste being the largest and most challenging to recycle.
While recycling solutions do exist and are employed in Europe, Asia and North America, the processing capacity for the expected surge is still too low. Lead acid battery (LAB) recycling benefits from a long history and a well-developed processing network across most continents.

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.
These studies demonstrate the viability of ammonia leaching as a method for extracting lead from various ores and compounds and underline the importance of specific parameters such as the type of ammonium salt, solution concentration, temperature, and leaching time.
