Metal Extraction, Production, and Purification

Our main area of expertise lies in the development, optimization, and evaluation of hydrometallurgical and pyrometallurgical processes. We particularly focus on methods suitable for processing and neutralizing metal-containing solid and liquid waste materials. Additionally, we offer techniques based on electrolysis and other reduction/oxidation processes for metal extraction and purification.
