Description of the research topic:

There are a number of types of the waste materials arising from the industrial production or from communal collection which can be used for extracting valuable metals. However, the value of the metal obtained depends also on its purity. The research is focused on the extraction of non-ferrous, precious or rare metals of high purity from the by-products of electronic or metals processing industries or from the collected wastes of modern technical or electronic devices. For this purpose, the media of mineral acids and other common or complexing aqueous solutions, the separation selective precipitation and controlled cathodic reduction of ions must be developed in coordination. The tasks belong to the technical phases of leaching, solution purification and the extraction from the electrolyte solutions. Concerning each of these technical phases, the goal is to work out the optimal process by determining the equilibrium and kinetic characteristics of the implied reactions. For this to achieve, exploring and utilizing the complex formation, redox transformation, ion-exchange and electrode kinetic processes of the ions may provide the possibilities.
