Deepocean mineral deposits as a source of critical metals
Marine mineral deposits offer new sources of metals Base and industrial metals include Cu, Ni, Zn, Mn, Co Rare metals include Au, Ag, Mo, Te, Pt, Zn, W, Nb, Marine minerals include seadredged and seabed minerals Seadredged minerals are normally extracted by dredging operations within coastal zones, at depths of about 200 Deep sea mining

Seafloor Minerals The seafloor contains deposits of minerals that we we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus These The discovery of metalrich hot springs on the ocean floor has spawned a new mineral exploration industry Also known as black smoker chimneys or seafloor Deepsea ore deposits Nature Geoscience

Global distribution of the three primary classes of metalrich deepocean mineral deposits: seafloor massive sulfides (SMS); ferromanganese (FeMn) nodules; The four best known polymetallic nodule fields are the Clarion–Clipperton Zone (CCZ), Peru Basin, Penrhyn Basin (including the Cook Islands EEZ) and Central Deepocean polymetallic nodules as a resource for critical

Hydrothermal Mineral Deposit an overview ScienceDirect
Hydrothermal Vents at MidOcean Ridges☆ RM Haymon, in Reference Module in Earth Systems and Environmental Sciences, 2014 Structure, Morphology, and Size of Deposits A typical hydrothermal mineral deposit on an unsedimented midocean ridge crest accumulates directly on top of basaltic or ultramafic rock On sedimented ridges, Sites Ocean mining sites focus on large areas of polymetallic nodules or active and extinct hydrothermal vents at about 3,000 6,500 meters deep The vents create sulfide deposits, which collect metals such as silver, gold, copper, manganese, cobalt, and zinc The deposits are mined using hydraulic pumps or bucket systems An additional site that is Deep sea mining
Criteria for recognition of hydrothermal mineral deposits in
Hydrothermal mineral deposits in oceanic crust include metalliferous sediments and encrustations and massive sulfides The occurrence of these deposits is explained by the hypothesis that they are concentrated at the discharge zones of high intensity subseafloor hydrothermal convection systems involving the circulation of sea water through oceanic Similar to some other countries such as China, the quest for minerals in the deep sea has been on India’s radar for some time now Recently, in June 2021, it got a significant boost as the Indian government approved a ‘Deep Ocean Mission’ to explore the ocean for resources and develop deepsea technologies for sustainable use of ocean India’s deep seabed mining plans gear up for a dive
Deepsea mineral deposits as a future source of critical metals,
Deepocean mineral deposits also provide valuable information on the evolution of the earth, seawater, and insights into the past global climate history Figure 1 presents an overview of different types of major deepsea minerals, which are described in a more detailed way in the following:The presence of mineral deposits in deepsea domain was totally unknown to the humans before 1870s The discovery of marine manganese nodules commences with the voyage of the HMS Challenger, 1872–1876, and for the first time on 18 February 1873 approximately 300 km southwest of the island of Ferro in the Canary DeepSea Mineral Resources and the Indian Perspective

Mineral Deposits in the Sea As a source of minerals, the ocean has been little exploited relative to its potential The major reasons for this default are probably a lack of public information as to what is in the ocean in the way of economically exploitable mineral deposits and the extreme caution with which investors and industryGandhinagar, UPDATED: Feb 14, 2023 23:58 IST Vast mineral deposits in the Indian Ocean can make India selfsufficient in nickel and cobalt, a top official of the International Seabed Authority (ISA) said on Tuesday Nickel and cobalt are critical ingredients in the lithiumion batteries used in most electric vehicles, which are zero Minerals in Indian Ocean can turn India selfsufficient in nickel
Geophysical Methods for the Mapping of DeepSea Mineral Deposits
In the deep ocean, geophysical methods are a key exploration tool for finding and delineating these resources The widest range of geophysical tools have been applied to the mapping of SMS and nodule deposits, and these provide case studies of the methods and instruments applied in the regional mapping, target generation and testing However, their tonnage throughout the global ocean is poorly known and grade/tonnage comparisons with landbased deposits would be premature The Clarion–Clipperton Fe–Mn Nodule Zone (CCZ) in the NE Pacific and the prime Fe–Mn crust zone (PCZ) in the central Pacific are the areas of greatest economic interest for nodules Deepocean mineral deposits as a source of critical metals for

Deepsea mining: plundering the seafloor’s minerals
These metalcontaining deposits are located around midocean ridges where the sea floor is, or was, volcanically active Mineralrich 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 Phone 8314607419 Little is known about marine mineral deposits in the Arctic Ocean, an ocean dominated by shallow areas of continental shelf and deep basins with limited circulation USGS scientists and their colleagues have published the first comprehensive paper on this subjectUnusual Mineral Deposits Record the Unique History of the Arctic Ocean
