Revision of Deep seabed mining has potential to be significant source of strategically valuable rare earth elements from Mon, 07/29/2013 - 23:35

Quicktabs: Arguments

Until a decade ago, the United States was 100 percent self-reliant for rare earth production, with domestic companies producing enough to supply U.S. manufacturers. Over time, however, U.S. production was halted as it became economically and environmentally cost prohibitive.

Companies in various countries – including the United States – are looking at reopening closed mines and developing new deposits, but these efforts could take a number of years to fully come on line.

The deep seabed offers a new opportunity for the United States to gain steady access to these vital rare earth minerals. Polymetallic nodules are located on the deep ocean floor. These nodules typically contain manganese, nickel, copper, cobalt and rare earth minerals. However, U.S. companies cannot actively pursue claims in the areas where these nodules are dense unless the U.S. ratifies the Law of the Sea Treaty.

Advances in deep sea resource exploration and exploitation technologies have also given rise to the prospect of accessing seabed resources not only within areas of outer continental shelf but in deeper waters and areas beyond national jurisdiction. While developments in the area are proceeding apace, notably in respect of the Clarion-Clipperton Zone in the Equatorial North Pacific Ocean and in the Central Indian Basin of the Indian Ocean,n areas of outer continental shelf subject to national jurisdiction are likely to be particularly attractive areas for development from the perspective of the coastal states, which hold sovereign rights over these areas. Indeed, it has been estimated that the Clarion-Clipperton Zone alone holds more than 27 billion tonnes of nodules containing of the order of 7 billion tonnes of manganese, 340 million tonnes of nickel, 290 million tonnes of copper and 78 million tonnes of cobalt as well as rare earths needed for the production of many hi-tech products such as smart phones.78 This led the International Seabed Authority's (ISA) Legal Counsel, Michael Lodge, to comment in May 2013 that "We are on the threshold of a new era of deep seabed mining."79 While the figures suggested may appear extraordinary, there seems little doubt that interest in the exploitation of these resources will be sustained so long as commodity prices remain high. The ISA's approval of exploration plans for the development of cobalt-rich manganese crusts by Chinese and Japanese concerns during its nineteenth session in July 2013 also appears to bear out the seriousness of this interest.80

It has long been known that the ocean might provide a wealth of rare earths. Sea-floor hydrothermal vents pump out rare-earth elements dissolved in their hot fluids. And these elements and others accumulate in potato-sized lumps, called manganese nodules, on the sea floor. The elements also build up in sea-floor mud; but only a few spot measures of this source of rare-earth elements have previously been made.

Kato and his colleagues set out to perform a widespread assessment of this possible resource. They looked at 2,000 samples of sediments taken from 78 sites around the Pacific, and found rare-earth concentrations as high as 0.2% of the mud in the eastern South Pacific, and 0.1% near Hawaii. That might not sound like much, but those concentrations are as high as or higher than those at one clay mine currently in operation in China, they point out. And the deposits are particularly rich in heavy rare-earth elements — the rarer and more expensive metals.

Some of the deposits are more than 70 metres thick. The authors estimate that an area of 1 square kilometre around a hotspot near Hawaii could hold 25,000 tonnes of rare earths. Overall, they say, the ocean floor might hold more than the 110 million tonnes of rare earths estimated to be buried on land.

Seabed mining, in the Arctic and elsewhere, is also becoming an important strategic interest for the United States. U.S. companies increasingly seek to engage in seabed mining for minerals such as rare earth elements and cobalt that are critical to the broad U.S. economy and used in producing defense assets. However, as long as the United States remains outside the international legal protections afforded by LOSC, the private sector remains hesitant to invest in seabed mining – investments that would reduce U.S. vulnerabilities to external pressure and supply disruption. Indeed, since few suppliers provide such minerals and they are prone to intentional or unintentional disruptions and price spikes, increasing U.S. production will help prevent suppliers from exerting political and economic leverage over the United States and its allies.22

The second economic benefit I would like to highlight relates to mining in the deep seabed areas beyond any country’s jurisdiction. Only as a Party to the Convention could the United States sponsor U.S. companies like Lockheed Martin to mine the deep seabed for valuable metals and rare earth elements. These rare earth elements – essential for cell phones, flat-screen televisions, electric car batteries, and other high-tech products – are currently in tight supply and produced almost exclusively by China. While we challenge China’s export restrictions, we must also make it possible for U.S. companies to develop other sources of these critical materials. They can only do this if they can obtain secure rights to deep seabed mine sites and indisputable title to minerals recovered. While we sit on the sidelines, companies in China, India, Russia, and elsewhere are securing their rights, moving ahead with deep seabed resource exploration, and taking the lead in this emerging market.

India has joined the race to explore and develop deep-sea mining for rare earth elements — further complicating the geopolitics surrounding untapped sources of valuable minerals beneath the oceans. The country is building a rare-earth mineral processing plant in the east coast state of Orissa and it is spending around US$135 million to buy a new exploration ship and to retool another for sophisticated deep-water exploration off its coast. The Central Indian Basin, for example, is rich in nickel, copper, cobalt and potentially rare-earth minerals, which are highly lucrative and used widely in manufacturing electronics such as mobile phone batteries. They are found in potato-shaped nodules on the deep-sea floor. "These nodules offer a good solution to meeting the nation's demand for metals," C. R. Deepak, head of the deep-sea mining division at the National Institute of Ocean Technology (NIOT), Chennai, told SciDev.Net.

The world economy, still suffering from the financial crisis, is currently experiencing increasing commodity prices. Industrial associations and governments are monitoring patterns of supply and demand, not only for standard minerals like iron, but also for high-value metals (e.g., nickel, copper, titanium, gold) and rare earth elements (REE) like yttrium, indium, gallium, neodymium, and germanium (Kato et al. 2011) which are important for semi-conductors, photovoltaics, lasers, liquid crystal displays, fiber- optic cables, and other high-tech products used in both civilian and military applica- tions. The demand for raw materials is expected to double in the next 25 years. The EU has identified a list of 14 out of 41 critical raw materials2 which are irreplaceable in key industries. The supply risk is due to the fact that a high share of production comes from China,3 Russia, South Africa, the Democratic Republic of Congo, and Brazil. This production concentration cannot easily be substituted for or augmented by other sources. The political–economic stability of some of the producing states is questionable and, in the case of Congo, nearing collapse. The list of failing states will grow where humanitarian and environmental risks may get completely out of control. The risks for the supply chains are self-evident: old and newly industrialized states are competing over prices and access rights to the remaining raw materials, while the low-hanging fruits have been picked. As a consequence, interest in marine mineral resources is growing again. With only 29% of the world's surface being land and 71% being sea, there is every reason to believe that terrestrial minerals occur in deposits on and in the seabed, as well. The Pacific Ocean alone is larger than all land masses on earth.

"Mining the Seafloor for Rare-Earth Minerals — William J. Broad — New York TimesNovember 09, 2010

For decades, entrepreneurs have tried to strike it rich by gathering up the manganese nodules that carpet the global seabed but until now they have not been able to prove the economic viability of these ventures. The nodules turn out to contain so-called rare-earth minerals — elements that have wide commercial and military application but have hit a production roadblock.
