mineral deposits on the seafloor

Deep-Ocean Mineral Deposits - Elements

A key question for the future management of the oceans is whether the mineral deposits that exist on the seafloor of the deep ocean can be extracted without significant adverse effects to the environment. The potential impacts of mining are wide-ranging and will vary depending on the type of metal-rich mineral deposit being mined.

Mineral Deposit - an overview | ScienceDirect Topics

Mineral deposit models are "an organized arrangement of information describing the essential characteristics or properties of a class of mineral deposits" (Stoeser and Heran, 2000).The mineral deposit/belt model contains systematically arranged information describing some or all important characteristics, variations within a group, and type of known deposits.

Seafloor mining: the DeepGreen method

Aug 02, 2017· Unlike deepsea mining of crust or seafloor massive sulphides, nodules sit semi-submerged on the seafloor and, therefore, do not require intensive mining. "Seafloor Polymetallic nodules are mineral deposits found on the seafloor that can look like fields of potatoes," says DeepGreen head of environment and social performance Dr Samantha Smith.

Reporting of seafloor Mineral Resources – AMC Consultants

Reporting of seafloor Mineral Resources. Interest in the exploration and mining of seafloor mineral deposits continues to grow, spurred on by a range of factors including decreasing deposit grades on land and the development of new subsea mining technology.

Seafloor Mining - Woods Hole Oceanographic Institution

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 .

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. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper ...

Hydrothermal mineralization at seafloor spreading centers ...

The recent recognition that metallic mineral deposits are concentrated by hydrothermal processes at seafloor spreading centers constitutes a scientific breakthrough that opens active sites at seafloor spreading centers as natural laboratories to investigate ore-forming processes of such economically useful deposits as massive sulfides in volcanogenic rocks on land, and that enhances the ...

These metal-containing deposits are located around mid-ocean ridges where the sea floor is, or was, volcanically active. Mineral-rich superhot water from underlying magma meets cold deep seawater and forms a crust on the seafloor at a depth that is often richer in minerals, particularly copper, than can be found in land deposits.

Seafloor massive sulfide deposits - Wikipedia

Seafloor massive sulfide deposits or SMS deposits, are modern equivalents of ancient volcanogenic massive sulfide ore deposits or VMS deposits. The term has been coined by mineral explorers to differentiate the modern deposit from the ancient. SMS deposits were first recognized during the exploration of the deep oceans and the mid ocean ridge spreading centers in the early 1960s.
