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
Keywords:
Hard Metal, Critical Metals, Recycling, Cobalt, Maleic Acid
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
Microbial inoculum production for bioleaching of critical metals from tailings
Butu A., (Corresponding) RODINO S., (Corresponding) BUTU M.
Topic:
Recycling of materials to new products
In this paper, research is presented regarding the development and testing of strategies to identify the optimal solutions for the production of microbial inoculum for the bio-recovery of critical metals from tailings. The versatility and diversity of biotechnologies available offer the opportunity...Read more
