Biorecovery of metal sulfides from leachates obtained through zinc-carbon battery recycling

(Corresponding) Retka J., Uhrynowski W., Zhendong Y., Karczewska-Golec J., Bajda T., Drewniak L., Debiec-Andrzejewska K.
Topic: 
Solid waste management
One of the most commonly used methods of recycling of spent zinc-carbon batteries is hydrometallurgical leaching with sulfuric acid. The technology is highly efficient and enables the recovery of the majority of deposited metals. Unfortunately it also generates leachates that remain after the...Read more

A new sustainable approach in recovering Cobalt from “hard metal” production by-products

Amadou O., DE GAUDENZI G., MARCHESELLI G., PIREDDA M., (Corresponding) SERPE A.
Topic: 
Hazardous waste management
The present work shows the capability of Maleic Acid solutions to tune the amount of Co in cemented carbide-based recovery powders with a Co content exceeding the threshold (10% Co) for industrial manufacturing in Hard Metal production and required by safety regulations. Maleic acid solutions react...Read more
