BrineMine: Extraction of valuable substances and drinking water from geothermal sources in Chile

Membrane distillation for desalination and mineral extraction from geothermal brine wells using geothermal energy. The “BrineMine” project in Chile has been running since March 2019. Since then, a SolarSpring MD plant has been treating geothermal water in the Andes at an altitude of over 4,000 meters above sea level in such a way as to obtain drinking water on the one hand and to separate rare metals on the other.

The work of SolarSpring takes place in close consultation with Fraunhofer ISE.

The development of new fields of application, such as the treatment of geothermal brines, is a very
is a very good opportunity for SolarSpring to become active in a new market on the one hand and to
market on the one hand and to further develop its own technology for current markets on the other.
