Hydrometallurgy
The Hydrometallurgy department focuses on the utilization of aqueous solutions for the recovery of valuable metals from ores, concentrates and recycled or residual materials, in an economically viable and environmentally sustainable manner. Hydrometallurgical processes include leaching, precipitation, cementation, ion exchange, absorption and solvent extraction.
Department’s main activities are:
Research and development of hydrometallurgical methods of processing
Studies on aqueous chemistry, thermodynamics and kinetics in hydrometallurgical processes
Development and design of hydrometallurgical flowsheets
Design and execution of laboratory and pilot scale trials for process testing and optimization
