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

Selective Recovery

Ion-selective polymer inclusion membranes (PIM)

Did you know that our #sea4value "brines and seawater catalogue" covers around 150 samples from locations worldwide?

The seawater from the Mediterranian at Vasilikos, Greece, has for example a relatively high amount of boron of 8.8 mg/l.

More info:

Did you know that 1l of seawater brine collected from the Mediterranian Sea in Oran, Algeria, contains 1.6 g of Mg, 0.5 g of Ca, 5.9 mg of B and 200 ug of Li.

We analysed 30 elements from 150 brine samples.
