Mining of deep-sea seafloor massive sulfides: A review of the .

Abstract. Seafloor massive sulfide (SMS) deposits form in a suite of hydrothermal settings across a range of depths. Many deposits are of a tonnage and mineral grade comparable to land deposits and are attractive to mining companies. Economically viable deposits can be either active or inactive, with different biological.

Ocean Exploration – The Mineral Resources Perspective

actively exploring for metals in the deep oceans. Other countries (Papua New Guinea, Fiji, Tonga) have leased portions of their EEZs for exploration of seafloor hydrothermal ore deposits. Because the oceans cover more than 70% of the Earth's surface, many expect them to contain vast quantities of mineral resources [1-3].

Chinese Deep-Sea Sub Reports Large Mineral Deposits In Indian .

Mar 19, 2015 . The Chinese government says Jiaolong's discovery could help jumpstart research into seafloor sulfide deposits as a resource for various metals. Although China has 95 percent of all rare metals on Earth, it has recently become the fifth country in the world to develop deep-sea exploration technology.

Generation of Seafloor Hydrothermal Vent Fluids and associated .

metal-rich deposits (possible analogs to ore deposits present on land), and (4) provide energy sources for biological communi- ties in the deep sea. The discovery of seafloor vents was a result of a number of factors. It came about in part through hypothesis-driven inquiry, which predicted that hydrothermal activity at mid-.

These Fearsome Robots Will Bring Mining to the Deep Ocean

Feb 27, 2017 . Seafloor massive sulfides are rich in metals such as copper, gold, silver, and zinc. It's this kind of trove that Nautilus Minerals plans to excavate. The company will send robots weighing hundreds of tons to crawl over the seafloor on treads, chewing up the hard deposits and slurping up the pulverized slurry.

Deep Sea Mining - Massachusetts Institute of Technology

Sea floor deposits are much more concentrated than those on land, meaning a significantly smaller volume of earth must be moved to extract the same amount of usable minerals. Less materials consequently have to be processed, which is what causes most of the environmental problems in the first place. Also, current.

The Ocean Could Be the New Gold Rush

Jul 13, 2016 . The valuable materials are likely to occur in higher concentrations on the seafloor than in many land-based mines, experts predict. They appear in nodules that litter the seafloor and in crusts of manganese or sulfide deposits, especially near hydrothermal vents. These minerals can be found between a few.

Deep Sea Mining a New Ocean Threat | HuffPost

Oct 20, 2015 . There are currently three main types of deep sea mineral deposits of interest to industry and governments: 1. . Seafloor Massive Sulphide (SMS) deposits are found beneath deep sea hydrothermal vents along the 67,000 km of volcanically active mid-ocean ridges and back arc basins, between 1,500 m.

Future of mining may be on the ocean floor - CNBC

Jun 15, 2015 . Nautilus Minerals wants to be the world's first deep-sea mining company, and says the ocean floor is the best and safest place to get needed minerals. . And deep sea mines would not displace communities that might be living on rich deposits or near processing facilities, the report said. "With few.

The abundance of seafloor massive sulfide deposits

seafloor massive sulfide deposits were known on the mid-ocean ridges; by the early 1990s more than 150 sites had been discovered (Rona and. Scott, 1993). Because the ocean floor covers more than 70% of Earth's surface, many expect the oceans to contain a proportionate amount of the world's mineral resources,.
