Head of junior research group (FAU): Enrichment of critical metals in the Earth’s crust
Research Interests
Critical metals are rare in the Earth’s crust and positive anomalies of these elements only occur in geographically restricted areas. The wide economic application of these elements in electronics and renewable energies gives them a strategic importance. However, supplying these critical and energy critical elements for the green transition is a growing challenge. Hence, it is important to develop new concepts with respect to critical element sourcing, fractionation and precipitation to ultimately define the magmatic-hydrothermal prerequisites that allow an enrichment of these rare commodities in the Earth’s crust.
Many of these metals and metalloids are hosted in hydrothermal sulphides like pyrite either in solid solution due to lattice substitution or as inclusions on the micro- to nano-scale. Little is known about the incorporation mechanisms for many of these elements, however, this information is vital to achieve high recovery rates, and therefore an efficient and sustainable way of mining and processing.
