"We show that rare-earth elements and yttrium are readily recovered from the mud by simple acid leaching, and suggest that deep-sea mud constitutes a highly promising huge resource for these elements," they wrote. "We estimate that an area of just one square kilometer, surrounding one of the sampling sites, could provide one-fifth of the current annual world consumption of these elements," the scientists report.Īnd, the scientists say, the rare earths might not be difficult to extract. Yasuhiro Kato and his colleagues at the University of Tokyo say they surveyed 78 sites on the Pacific Ocean floor and found high concentrations of rare-earth elements and the metal yttrium. Key raw materials necessary for modern devices such as cell phones, laptop computers and flat-screen TVs may be found in abundance on the ocean floor, Japanese scientists report in the journal Nature Geoscience.
