Deep-sea mining | IUCN

• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.

Deep sea mining - Wikipedia

Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 meters or greater. As of 2021, the majority of marine mining efforts are limited to shallow coastal waters only, where sand, tin and diamonds are more readily accessible. There are three types of deep sea mining that have generated great interest: polymetallic nodulemining,

Seafloor Mining - Woods Hole Oceanographic Institution

Seafloor Mining. Hot, buoyant, mineral-laden fluids rise from deep within ocean crust and mix with cold seawater. That triggers the precipitation of minerals that form deposits near and on the seafloor. Precipitating minerals also form seafloor "chimneys," and mineral particles in the fluids venting at the seafloor make the fluids look like smoke.

Deep Sea Mining

Deep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs).
