Rare earth elements like yttrium are hard to extract from the ground , but they ’re essential ingredients in flat cover and consumer electronics . Now a mathematical group of researchers have give away monumental deposits of these component in mud on the deep sea floor . They trust we could bulge mining ocean clay to build more impertinent phones .
In this map of the Pacific Ocean ( get through to expand ) , you may see the sites where the scientist found mud impregnate with Y and other valuable component . Their discovery could usher in a uncommon land ingredient rush — on the bottom of the sea .
Geologist Yasuhiro Kato and colleagues took 2,000 deep mud samples from 78 different sites throughout the Pacific Ocean , psychoanalyze them using an X - ray of light fluorescence mass spectrometer , and discovered that they were deep in rare earth elements . They used acid leaching — acontroversial techniqueused to mine the metals on juiceless nation — to pull rarefied globe elements from the clay . base on the amounts of these element they found , the researchers argued that the seafloor might be a rich imagination for the element . In a newspaper published this week in Nature Geoscience , they argue :
We estimate that an orbit of just one square klick , surrounding one of the sampling situation , could provide one-fifth of the current one-year cosmos wasting disease of these elements .
They believe the component are so wide propagate across the Pacific because they ’ve been disperse there over millions of age from two active hydrothermal vents , the East Pacific Rise and Juan de Fuca Ridge . Over time , particles from those vent have swan on currents , and been metabolized by sea creatures , into the rare earth elements that are so difficult to mine on body politic without using techniques that many scientists have criticized for destroying wildlife and polluting rivers .
It ’s unclear how mining deep sea mud would be accomplished . Would undersea robots scoop up up monolithic amount of money of mud and bring it to the surface , to be Lucy in the sky with diamonds leach in processing plants ? Would we set up up undersea mining metropolis , or use platforms alike to those for oil colour oil production ? It ’s easy to imagine these mining operations could be equivalent to clear - write out 5 solid km of the sea base every twelvemonth — or even more , as requirement for these elements is only probable to get .

What ’s even more unclear is how deep ocean mud mining could be accomplished without destroying the delicate ecosystems at the bottom of the ocean , including precious coral and other creatures who are critical to the wellness of sea environments . Look carefully at the mathematical function above . You might be seeing a visual modality of tomorrow ’s mining industry .
