Minerals Webinar | Critical Metals Extraction Processes for a Greener Future, 21 August 2025
Today, we are experiencing rapid growth in the number of initiatives contributing to a sustainable energy transition. However, in many cases, there is a limited supply of critical metals to support future demand for manufacturing devices for electric transport, green energy production, and the ever-increasing consumption of communication and entertainment gadgets. From this perspective, it is imperative to develop new routes to exploit atypical (non-metallurgical) sources of metals, thereby lowering the gap between future demand and the expected supply and avoiding the hindrance of energy transition goals. In this context, the use of complex raw materials in the metallurgical industry, such as urban residues, low-grade mineral occurrences, as well as industry wastes (slags) and effluents, for example, is not only desirable but necessary in order to achieve such goals. Moreover, thermodynamic and kinetic modeling processes, as well as transport phenomena related to such challenging reaction systems, provide important foundations for the development of efficient extraction routes, supporting efficient and economically viable plant and equipment projects.
