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

Biomining - recovery of high-tech critical metals

BUTU A., RODINO S., (Corresponding) BUTU M.

Topic:

Circular economy and industrial symbiosis

Critical metals were defined as those metals essential for high-tech, medical and defense industry but with low availability due to uneven geographical distribution, thus resulting a high price volatility. The challenge of the future is to assure a stable supply of critical materials and implicitly...Read more
