BGR performs duties in the following fields of scientific research: mineral resources, energy resources, groundwater, soil, final disposal of radioactive waste, subsurface use, nuclear test ban, geo-hazard assessment and geoscientific data. In the Sub-Department „Geology of Mineral Resources“ and in the work unit „Technical Mineralogy and Clay Mineralogy“, deposits of mineral resources as well as residues from mining and mineral processing are studied. Of importance for the project PyroLith are especially the mineralogical and geochemical research activities at BGR under the aspect of secure supply of high-tech metals (e.g. Li, Co) for the industry. In the field of ore deposit research, a modern analytical equipment and many years of experience are present. The tasks of the laboratory for technical mineralogy include the further improvement of the methods for quantitative analysis of mineral compositions of geological samples (SEM-based automated mineralogy; Rietveld analysis).
