About Deep-Sea Mining

DSCC Position Statement on Deep-Sea Mining Amongst the riches of the seabed, deeply embedded into its ecosystems, are minerals such as copper, cobalt, nickel and manganese. Their potential industrial value means that prospectors are keen to extract them, so a new, highly speculative, deep-sea mining industry is emerging. Three types of mining are planned: Sucking up […]

Why can''t people dig too deep underground?

The short answer is stability and cost. The deeper you go, the more challenging it is to transport the materials you''ve drilled out. The Earth''s crust is miles deep, even if you''re talking about oceanic crust instead of continental crust. For ocea...

Deep-Ocean Mining: Technologies For Manganese Nodules And ...

This paper reviews research, development and design aspects of recent technologies for deep-ocean mining systems to recover manganese nodules and cobalt-rich manganese crusts from the seafloor at an 800-6,000-m depth. It also discusses selective technological challenges. The manganese crust is characterized on the basis of preliminary data.

Subsea Mining

Browse Dredging Equipment Contact Us For Fast Quote. Subsea mining, or deep sea mining, is a method of retrieving minerals from the ocean floor. Deepsea mining operations typically occur at depths of 4500 ft. to 12,000 ft. around areas with metallic nodules, as well as areas with high levels of geothermal activity.

Ferromanganese Crust | West Coast Placer

Ferromanganese crusts typically occur in the vicinity of underwater volcanoes called seamounts or near hydrothermal vents. Crusts with mineral grades that are of economic interest are commonly found at depths between 800m and 2500m. Ferromanganese Crust. Ferromanganese crusts are composed primarily of iron and manganese, hence the name.

Living With Deep-Sea Mining

 · Deep-sea hydrothermal vents form when seawater, under enormous pressure, percolates through the earth''s crust and comes in contact with a source of intense heat, most often in the form of magma. This superheated seawater is expelled through the vent, similar to a terrestrial geyser, as chemically-enriched vent effluent.
