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

Evaluation of industrial wastes as active materials in permeable reactive barrier for acid mine drainage remediation
Sanchez D., Lopez-Bellido J., Acosta I., Rodriguez L., Villaseñor J., (Corresponding) Fernandez-Morales J.
Topic:
Hazardous waste management
The aim of this work was to evaluate the use of agricultural and industrial waste materials as reactive agents into Permeable Reactive Barriers (PRB) for Acid Mine Drainage (AMD) remediation. Laboratory-scale columns containing Volcanic Scoria (VS) as porous fill material and approximately 18% w/w...Read more
