Lead acid battery (LAB) recycling benefits from a long history and a well-developed processing network across most continents. Yet, LAB recycling is subject to continuous optimization efforts because of increasingly stringent regulations on process discharge and emissions.
The innovative cleaner metallurgical process for one-step extraction of lead from spent lead-acid battery paste via reductive sulfur-fixing smelting is technically feasible. This new technique is characterized by high comprehensive recovery of valuable metals, elimination of SO 2 emission, energy conservation and environment-friendly.
Typically, the recycling technologies for the recovery of lead from spent lead paste can be based on both hydrometallurgical and pyrometallurgical processes. Recycling through hydrometallurgy basically consists of the acid or base leaching of scrap to put the metals in a solution [ 2, 4 ].
Modeling plays a key part in the development of reliable, efficient extraction processes for battery materials. In “CFD-PBM Simulation and PIV Measurement of Liquid–Liquid Flow in a Continuous Stirring Settler,” Guo et al. investigate optimization opportunities for widely used mixer settlers.
In “Sulfation Roasting Mechanism for Spent Lithium-Ion Battery Metal Oxides Under SO 2 -O 2 -Ar Atmosphere,” Shi et al. develop a proof of concept for LIB processing via the direct sulfation roasting of synthetic LiCoO 2 followed by water leaching.
While typically processed by destructive methods such as crushing, the authors introduce a new automated sequence which allows separation of cathode sheets, anode sheets, separators and aluminum film. This nondestructive process provides new opportunities for downstream treatment of the LIB.
