Integrated diffusion dialysis precipitation - Cementation for selective recovery of leaching chemicals and metal values from electroplating sludge

摘要

The hydrometallurgical valorisation of electroplating metal hydroxides sludge was investigated here. It proposes a complete solution. The hazardous solid waste is both an environmental and an economic global issue. It is considered as a challenging scientific topic. This work aims to recover selectively the leaching acid excess and metal values.
