6 FAQs about [Lead-acid battery hydrometallurgy]
How to recover lead from spent lead-acid battery paste?
Herein, a novel direct leaching-electrowinning process has been proposed to recover lead from spent lead-acid battery paste. Calcium chloride was used as the leaching agent and iron sheet was used as a soluble anode.
How are lead-acid batteries separated?
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.
What is a green lead hydrometallurgical process?
A green lead hydrometallurgical process based on a hydrogen-lead oxide fuel cell. Nat. Commun. 4:2178 doi: 10.1038/ncomms3178 (2013). Roberts, H. Changing patterns in global lead supply and demand. J. Power Sources 116, 23–31 (2003).
