Japanese Team Finds New Source of Rare Earth Elements
gyaku_zuki writes "As reported in the BBC, a Japanese survey team has discovered 'vast' quantities of rare earths in international waters in the Pacific Ocean. The search for alternative sources of these expensive elements (used in common consumer electronics including mobile phones) was intensified recently after a territory dispute with China, which produces more than 90% of the world's rare earths, resulted in China blocking export to Japan."
You're talking about the US, right?
China only has "90%" of the world's production because they were able to undersell and close suppliers outside China. As China restricts exports, the price climbs and the suppliers outside China resume business.
Media and some politicians have been spinning this one as if China holds 90% or somesuch assnumber of the world's resource. Is that still going on? I know it took BBC two weeks to wake up to that one.
it says the depth of this find is between 11,000 and 15,000 feet (3,500-6,000 meters). I'm not sure a mining operation at that depth is feasible, or at least, cost effective.
"First they came for the slanderers and i said nothing."
This is silly rare earths are not rare, just toxic to refine from ore.
China has the market cornered because they don't give a shit that they dump toxic sludge doing it.
As Woodrow Wilson warned, there is a military-industrial complex.
Wilson helped create the military-industrial complex. Eisenhower is the one who warned about it.
"I assumed blithely that there were no elves out there in the darkness"
China does not by any means have a lock on rare earth production, with wikipedia reporting the following:
China now produces over 97% of the world's rare earth supply, mostly in Inner Mongolia, even though it has only 37% of proven reserves.
There are two things going on here:
On #1 -- Indeed mining for rare earths in the US is expensive because of workplace and environmental health regulations, but it can be had for some price. If China restricts supply, price will rise and US mines can reopen while meeting rigorous US standards for environmental sustainability of rare-earth mining operations.
On #2 -- if China wants to restrict supply, that's fine -- but they're own factories are probably close to the world's largest users of rare earths for electronics. So it's not as if we won't be able to get our iPods.
US has better Chinese food.
There are no karma whores, only moderation johns
People hear "rare" and they think there must not be much of them. Well rare earths, aren't. I mean they are rare as opposed to, say, iron or silicon or aluminium, but they are not rare as in "very hard to find."
As the parent said, China produces most of them because they do it the cheapest. The US (and other countries) produced them in the past and can do so again in the future.
Now these under water deposits might be of interest because it sounds like they may be easier to process than what we have now. That could be useful. Even though the extraction will probably be more costly, if the refining and processing is cheaper, that could make them worth while.
However these are not something that is rare, contrary to the name.

THIS HAS BEEN KNOWN FOR *DECADES*!!!!!
Geologists have know for decades that the oceans contain a vast quantity of minerals, including rare earths. The Glomar Explorer, for example was built to secretly salvage a sunken Soviet submarine. However, a realistic cover story was needed, so the Government settled on saying that it was a ship designed to recover manganese nodules (which contain a smorgasboard of minerals and rare earths, in addition to high concentrations of manganese, hence the name) that cover the ocean floor.
The plausibility of the story rested in the fact that there *DO* exist extremely vast sources of minerals (including rare earths) on the sea floor.
Honest to God, why do highly educated and credentialed people keep overlooking things that have been known for a years?!
This should be grounds for revoking their credentials until they go back to school..... again.
I can already see the next "discovery" headline:
"Japanese researchers discover rotting fish stinks!"
Knowing Google's lust for data collection, the Soviet Union is still alive and well inside the psyche of Sergey Brin....
Rare earths are not rare. It was a horrible, horrible mistake to call them rare. Some of the elements in that family are more abundant than copper. They were coined 'rare' because as far as metals go, they are quite reactive, which makes them great for batteries, but also means they don't have much time to bond with eachother...which makes them great FOR BATTERIES! In essence, you do not find chunks of Cerium just laying around like you do, or did in some cases, as iron and boxite (aluminum) and copper. Thus they are usually found as minor, but significant, traces in other minerals and not all by themselves or as significant ores.
The largest mines prior to the mid 90s were located in the United States in Oregon, Brazil, and South Africa. There were literally Indiana Jones like warehouses full of 'rare earths' that were unneeded because the chemical properties of this family mean they are not found in huge chunks, but rather spread out in a given area. If you are digging for Lanthanum, for example, you'll end up with 'worthless' Neodymium and other metals. Prior to the mid-90s, these elements would often flip flop on the market as mines started pulling out different metals (Scandium vs Yttrium and Neodymium vs. Iridium)
China undercut global demand for the metals 20 years ago, and the World hasn't looked back since. It was an arrangement of convenience, as China started pulling out the damn stuff faster than the world could 'spend it.' No longer did lamp makers and battery manufacturers have to worry about ridiculous future contracts for rare earths. Prices stabilized quite dramatically, and the Wold loved it. China got a huge boost to a nascent technological and manufacturing industries due to the flood of foreign investment, as well as first dips on cheap metals.
The minute the so called 'Peak Earth' hits, and rare earths spike on the market because they have all 'disappeared', mines across the Globe will open up once again since it will be cost effective to sell the damn things.
So no, it will not be commercially viable to dig these elements out of the ocean floor for many many years. Keep in mind, the ocean floor is also full of gold nuggets, and the ocean itself as a vast amount of gold in solution. But just as it wouldn't be worth it to fly to the Moon where it made of gold, it isn't worth it to go panning for the stuff 1km below the ocean surface.
Anyway, 2.5 cents.
