Novel technologies
in seawater desalination plants to extract minerals and metals from seawater brines

Sea4Value brings together 16 partners from Spain, Germany, Italy, Belgium, Ukraine, Netherlands, Finland and Switzerland to develop and upscale technologies to sustainably mine raw materials from brines.

10 extracted minerals / metals

The main focus will be on separating, concentrating and crystallising Molybdenum, Magnesium, Scandium, Vanadium, Gallium, Boron, Indium, Lithium, Rubidium and Calcium.

10 technologies

Sea4Value will develop radical innovative technologies for pre-treatment, concentration, extraction, purification and crystallisation:

We aim to create a multi-mineral and modular process. @Eurecat_news is involved in the development of various technologies such as ion-selective PIMs to recover gallium or liquid rubidium or ionic-liquid solvent extraction to recover indium🌊

Exciting project progress! The ELS (Electrolytic System) pilot unit has been installed at the Wastewater Treament Plant in Gandia 🇪🇸! The pilot plant turns waste into a resource by using brines and metal waste to create sustainable coagulants for treatment of wastewater in-situ.
