6 FAQs about [Lead-acid battery chemical treatment method]

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 is lead-acid battery scrap treated?

Lead-acid battery scrap is generally treated in rotary drum furnaces using liquid fuel as an energy source. The reverberatory furnace and blast furnace or electric furnace combination is seen primarily in the USA.

Can slaked lime remove lead sulfate from Battery wastewater?

Multiple requests from the same IP address are counted as one view. In this study, we present a low-cost and simple method to treat spent lead–acid battery wastewater using quicklime and slaked lime. The sulfate and lead were successfully removed using the precipitation method.

Are conventional effluent purification processes used for the recovery of lead acid batteries?

The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.

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 can 'battery ready' lead oxide be recycled?

NUOVOpb, an EU-supported project, successfully separated the spent materials from LABs, ‘recovering’ them in a water-based recycling process to produce ‘battery ready’ lead oxide. The process offers a start-up cost around one seventh of existing LAB recycling and a comparable operating cost to existing recycling methods.
