Lithium, cesium, or even gold—in addition to energy geothermal waters can contain mineral treasures. In the BrineMine research project, researchers from Karlsruhe Institute of Technology (KIT) want to leverage this potential and support sustainable mining in Chile. Together with their partners, they are developing strategies and methods for extracting mineral resources directly in geothermal power plants. Here, not only energy and minerals are to be extracted, but also drinking water. Important process steps have already been successfully tested in a demonstration plant.
