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. Presently, the majority of marine mining efforts are limited to shallow coastal waters, where sand, tin and diamonds are more readily accessible.[1] There are three types of deep sea mining that have generated great interest: polymetallic nodulemining, polymetallic sulphide mining, and the mining of Cobalt-Rich ferromanganes

Deep-sea mining is the process of retrieving mineral deposits from the deep sea the area of the ocean below 200 m which covers about 65% of the Earth’s surface. There is growing interest in the mineral deposits of the deep sea.

Deep sea mining Wikipedia

Deep sea mining is a mineral retrieval process that takes place on the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface.

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.
