What is the importance of recycling lead from Wasted lead acid batteries?

Recycling lead from wasted lead acid batteries is related to not only the sustainable development of lead-acid battery industry, but also the reduction of the lead pollution to the environment.

How pyrometallurgy is used in recycling lead-acid batteries?

The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).

How much lead is in battery wastewater?

The average concentration of lead in wastewater is about 3–15 mg/L and the pH of wastewater falls in the range of 1.6-2.9 [ 9 ]. If the battery wastewater is not treated well before discharge to environment, lead can contaminate food and water, and be present in nature.

Does carbonation improve the removal efficiency of lead in battery wastewater?

The removal efficiency of lead was increased after using a carbonation step with 68% for quicklime and 69% for slaked lime. The carbonation process not only enhanced the lead removal efficiency in the battery wastewater but also reduced pH to meet requirements of environmental regulations.

How do you recycle lead from a battery?

Li W. et al 2023 Recycling lead from waste lead-acid batteries by the combination of low temperature alkaline and bath smelting. Separation and Purification Technology 123156 Pan J. et al 2016 Preparation of high purity lead oxide from spent lead acid batteries via desulfurization and recrystallization in sodium hydroxide.

Can lead-acid batteries be recycled?

Because lead is toxic to the environment and to humans, recycling and management of waste lead-acid batteries has become a significant challenge and is capturing much public attention. Various innovations have been recently proposed to recycle lead and lead-containing compounds from waste lead-acid batteries.
