Dyphavsmineraler

Norway’s slow-spreading ridges could host larger sulfide deposits than what we have uncovered up until now. Lessons from research at the Semenov hydrothermal field along the Mid-Atlantic Ridge could lead to enhanced understanding – and exploration strategies – in Norwegian waters.

Sokkeldirektoratet hevder store mengder gull og sølv finnes på havbunnen, men uten lønnsom utvinning er det bare tall. Begrepsforvirring skaper feil inntrykk, mener Arne Bjørlykke.

Sokkeldirektoratet og Universitetet i Bergen har påvist en ny sulfidforekomst langs Knipovichryggen vest for Svalbard. Tilstedeværelse av mineralet atacamitt bekrefter et høyt innhold av kobber.

Frustrated by the International Seabed Authority’s stalled progress on a deep-sea mining code, The Metals Company is turning to a 1980 U.S. law to fast-track its ambitions.

Recent deep-sea expeditions along the Indian Ridge have uncovered multiple active and inactive hydrothermal vent fields, pointing to potential deposits of polymetallic sulfides.

As seafloor sulfide deposits age and disintegrate, copper and other valuable metals can be washed away or concentrated in different layers. Two key minerals may serve as clues for finding the untapped resources.

Ensuring efficient extraction of valuable metals from seabed ore is crucial for the new industry’s viability.
