The future of mining is rapidly evolving, and new frontiers are opening such as deep-sea mining and extra-terrestrial resource exploration. GlobalData Thematic Intelligence February 26, 2024. As the world transitions …
According to deep-ocean-mining proponents, the seabed nodules could provide most of the minerals the world needs, with minimal impact. ... After a tour of a Chinese submersible-mining-tech factory ...
A brief observation of the developments in mining systems and technology in the past 2 to 4 years is presented. Discussions on the development of other deep-ocean resources that are somewhat similar to nodule production also include gas hydrates, Cobalt-rich manganese crusts, hydrothermal vents and deep-ocean water upwelling (DOW). Previous reviews of deep-ocean …
The UN observance of 2021-2030 as the Decade of Ocean Science for Sustainable Development, alongside the existing Sustainable Development Goal 14 (which aims to conserve and sustainably use ocean resources), presents an opportunity to accelerate efforts to develop strong, well-informed frameworks for deep-sea mining as a comprehensive …
Deep-sea minerals, including nickel, copper, manganese and cobalt, are crucial to building clean-energy technologies
Keywords: marine minerals, deep sea, biodiversity, battery technology, ocean governance, critical metals. Citation: Miller KA, Brigden K, Santillo D, Currie D, Johnston P and Thompson KF (2021) Challenging the Need for Deep Seabed Mining From the Perspective of Metal Demand, Biodiversity, Ecosystems Services, and Benefit Sharing. Front. Mar.
Deep below the sea lay critical minerals that are both high in value and demand. These critical minerals—such as cobalt, nickel, and manganese—are used in everyday devices like cellphones and cars. But they are hard to come by, and demand is expected to double or triple by 2030. Because of this demand, interest has turned toward the deep ocean seabed, …
The recent state of technological development in the countries that have joined deep-ocean mining since the '90s is reviewed in terms of readiness for the development of a commercial mining ...
Murky Guidance in the Muddy Ocean. Deep-sea mining could be a boon for job creation and clean energy technologies. However, mining in the sea poses similar environmental threats to those created by mining on land. …
Mining nodules from the deep ocean seabed could provide the metals crucial for today's EV batteries and renewable energy technology, but little is known about the harm it could cause.
Mining the ocean floor for submerged minerals is a little-known, experimental industry. ... Deep-sea mining technology is still in development but will probably include vacuuming nodules from the ...
Download Citation | Deep-ocean mining technology: Development II | The review is an update from the review presented at the OMS-2005 (Chung, 2005). It includes discussions on the technical issues ...
e360: Some mining companies say that metals from the ocean floor are needed for the rapid expansion of green technologies. They also claim that deep-sea mining is less destructive than land mining. Is there a green argument for this? Levin: Land mining is very destructive. But the footprint is much, much smaller.
But critics say that the expense and logistics of mining in the remote ocean — and transporting metals back to land — raise doubts about whether deep-sea mining can be profitable. Ms. Ms.
Japan is one among just a handful of nations actively pursuing deep-sea mining within its own waters. The country aims to be ready to mine by the late 2020s and could be among the first nations to ...
The sea-mining company is now designing the much larger Patania III—the first of what the company hopes will be a fleet of full-scale mining robots that will hit the ocean floor around 2028.
Deep-ocean polymetallic nodules (also known as manganese nodules) are composed of iron and manganese oxides that accrete around a nucleus on the vast abyssal plains of the global ocean 1,2,3,4,5,6
With the continuous development of science and technology, the 21st century is gradually realized to be the century of ocean, which covers about 71% of the earth's surface area [1]pared with the land, ocean contains a wide range of mineral resources, not only including the traditional oil and gas, but also the various mineral resources that have not been fully …
While the ocean is a major carbon sink, absorbing about 25% of all carbon dioxide emissions 1 and capturing around 90% of the excess heat 2 caused by humans, it also holds vast deposits of rare earth minerals. We've known about …
Deep-sea mining (DSM) is the process of excavating mineral deposits from the deep seabed. Currently, the mining technology developmental works for harvesting polymetallic nodules are in advanced stages, having had precedence through successful demonstrative trials during the late 1970s by many consortia of firms (Knodt et. al., 2016) from the USA, Canada, …
Supporters of deep-sea mining maintain that exploiting the sea floor is central to meeting transition mineral demand growth. Demand for copper and rare earth metals will grow by 40% in a net-zero by 2050 scenario, predicts the International Energy Agency (IEA), which expects demand for nickel, cobalt and lithium to grow by 60%, 70% and 90%, respectively.

In April 2021, Cdr. Gopakumar K. and his colleagues from the National Institute of Ocean Technology (NIOT) reached the central Indian Ocean with Varaha-1, a deep-sea mining machine. The 9.5-tonne machine …
Deep-sea mining is the process of exploring the deep seabed and retrieving minerals like cobalt and manganese (used in things like rechargeable batteries, smartphones, and steel), as well as gold, nickel, and rare earth elements. Private companies are designing and testing several technologies to explore and sample wide areas of the ocean floor.
Ocean mining has been developed since the 1950s, and deep seabed mining has seen a boom in the last decade. Many high-value deep-sea minerals have been discovered in a vast deep-sea area of 360 million km 2 with a water depth of more than 200 m (Miller et al. 2018).As the most valuable mineral resources of this century, deep-sea minerals are critical for high-tech …
Mining in parts of the Pacific Ocean was meant to benefit poor countries, but an international agency gave a Canadian company access to prized seabed sites with metals crucial to the green energy ...
NEW TECHNOLOGIES. Ocean technology, which is advancing at a pace never seen before, will also prove instrumental. Breakthroughs in autonomous systems and AI have the potential to completely rewrite how …
The review is an update from the review presented at the OMS-2005 (Chung, 2005). It includes discussions on the technical issues that have been already identified in the literature for manganese nodule production system design and on initial stages of crust mining concepts. It appears no new additional issues have yet been identified and solved. Recent discovery of the …
The seabed is considered one of the last mining frontiers. Yet offshore Namibia, De Beers has been commercially prospecting the sea since 2002. But how does marine mining for diamonds in Namibia's shallow waters …
ABSTRACT. 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 …
