Description
1. Product Overview
Lead Paste Residue is a secondary industrial material generated during the recycling and processing of lead-acid batteries. It primarily contains lead compounds such as lead sulfate, lead oxide, and metallic lead particles, making it a valuable feedstock for lead recovery and metallurgical processing. This material is widely used by smelters and battery recyclers seeking cost-effective raw material inputs for refined lead production. With rising global demand for recycled metals and circular supply chains, Lead Paste Residue represents a strategically important resource for sustainable lead recovery and industrial material efficiency.
