Due to low content of these metals in e-waste, they are...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
