Zero lead pollution process for recycling used lead acid batteries |
| abstract |
Described herein is a process for recycling of used lead-acid batteries. In an embodiment, the process includes contacting crushed non-metallic components with a reducing mixture comprising a nitric acid solution to reduce at least a portion of residual lead compounds and alloys. The lead in the portion of residual lead compounds and alloys is reduced from an insoluble +4 state to a soluble +2 state to form a slurry with a lead-rich filtrate. The process further includes filtering the slurry to separate plastics and separators from the lead-rich filtrate and contacting the lead-rich filtrate with sulfuric acid to obtain a lead sulfate paste and nitric acid. The process further includes processing the metal containing components to form a paste comprising sulfates of lead and other metals present in the metal containing components, contacting the lead sulfate paste and the paste comprising sulfates of lead and other metals with alkali to form a precipitate comprising oxides of lead, and contacting the precipitate comprising oxides of lead with a carboxylic acid to form soluble lead carboxylates. Soluble lead carboxylates are then processed to obtain lead monoxide. |
