Breakthrough solutions for the sustainable exploration and extraction of deep-sea mineral resources

Mineral resources are a key factor in the success of economies and societal progress. It is well known that high-tech metals such as indium, germanium, rare earths and cobalt, crucial for future technologies such as renewable energy and electric mobility, are enriched in the rocks of the ocean depths. .

About the project

The Blue Mining project addresses all aspects of the deep-sea mining value chain, from resource discovery to reserve evaluation and mining technologies to the legal and regulatory framework. Therefore, the explored deep mineral resources, mining plans and concepts, and technological developments of the Blue Mining project are analyzed with respect to economic feasibility. In addition to common approaches for the economic evaluation of mining projects, sustainability aspects such as primary resource efficiency are also taken into account.


Seafloor Spreading

It posits that new ocean floors are constantly being created around mid-ocean ridges at a rate of a few centimeters per year per ridge flank (i.e. tens of kilometers per ridge flank per million years ). Thus, on this model, most and perhaps all of the deep ocean basins on the surface of present-day Earth formed in the wake of drifting continents or continental fragments, with new oceanic crust being formed by a process of remarkably symmetrical accretion to ocean ridge crests. The ridges of the mid-ocean ridge are therefore the boundaries of the accretionary or building plates of the plate tectonic model, and the plates, which include the separating continents, expand as new oceanic lithosphere is added. to their trailing margins by the process of seafloor spreading. ....
