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:


Nanofiltration membranes for monovalent and multivalent ions separation


Calcium precipitation


Advanced membrane crystallisation


Advanced multi-effect distillation
