6 Frequently Asked Questions about “Hydrometallurgical lead-acid battery”
What are the components of spent lead acid battery?
There are four main components in spent lead acid battery: polymeric containers, lead alloy grids, waste acids and pastes. Among them, the pastes mainly comprise lead oxide (∼9%), lead dioxide (∼28%), lead sulfate (∼60%) and a small amount of lead (∼3%) (Zhu et al., 2012a).
Can lead paste be recycled from spent lead acid battery under vacuum?
Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.
Can pyrometallurgical and hydrometallurgic methods be used to recover lead?
