"China's monopoly over rare-earth metals could be challenged by the discovery of massive deposits of these hi-tech minerals in mud on the Pacific floor, a study on Sunday suggests.

China accounts for 97 percent of the world's production of 17 rare-earth elements, which are essential for electric cars, flat-screen TVs, iPods, superconducting magnets, lasers, missiles, night-vision goggles, wind turbines and many other advanced products."


"....But a new study, published in the journal Nature Geoscience, points to an extraordinary concentration of rare-earth elements in thick mud at great depths on the Pacific floor."

"A bigger question is whether the technology exists for recovering the mud at such great depths -- 4,000 to 5,000 metres (13,000 to 16,250 feet) -- and, if so, whether this would be commercially viable.

In an email exchange with AFP, lead author Yasuhiro Kato, a professor of economic geology and geochemistry at the University of Tokyo, said the response from mining companies was as yet unknown, "because nobody knows the presence of the (rare-earth) -rich mud that we have discovered."

"I am not an engineer, just a geoscientist," Kato said. "But about 30 years ago, a German mining company succeeded in recovering deep-sea mud from the Red Sea. So I believe positively that our deep-sea mud is technologically developable as a mineral resource."

Chinese military submarines cannot protect the mining site because they have a crush depth of around 800 feet.

America is the only country currently producing next generation high speed, maneuverable full ocean depth submersibles like the one shown.

Not endorsing anything unethical of course, just saying we've got the tool for the job.

Why send people down there? Absolutely retarded. Just use ROVs like they are used in deep see oil drilling operations, no problem to get to 5000m whith those and they work just as well as if someone was actually down there. Pump the shit up and process it. BAM.

You don't send people down there to mine. You send them down there to disrupt the mining operations. And you use people instead of ROVs because a piloted craft doesn't need a tether.

>> No.3333553

You do realize how unfeasible and stupid this would be just to get minerals?

There are probably dozens of countries that can produce rare earth elsewhere, on land, and much cheaper than what could be found here.

The only reason China has a dominance is that they monopolized the market early, and other countries did not develop/closed down existing mining.

War? No. If the goal was to wage war you'd just destroy the surface support ship.

This is a plausibly deniable way to constantly frustrate their efforts to mine. It's 2.5 miles down. If something goes wrong with their robot, who can say why?

Get a carrier sub just outside of their detection range, launch weaponized submersible which then cruises along the bottom until it locates the mining robot. Destroy robot, return to carrier, lurk away undetected.

I understand that you, personally, believe it's stupid. But the business case works out, which is why five nations (Canada, India, Australia, Japan and China) are now mining the sea floor.

The foremost seafloor mining company is Nautilus Minerals, currently retrieving precious metals like gold, silver and platinum from the Solwara 1 site in Papau New Guinea.

You misread my post. I said that's what we'd do if we *did* want to wage war, but that I would favor instead an approach which secures the minerals without costing human lives.

>>They cannot outrun a torpedo.

...Fired from a military submarine that cannot go deeper than 800 feet? I doubt the guidewire is even long enough to reach the target.

In this specific context, submersibles have a legitimate military use. They are the only vessels that can operate at the depths required. ROVs require a tether and surface support vehicle. Torpedos require a guidewire and are fired from subs with a crush depth of only 800 feet.

In the instance, under these specific circumstances, weaponized submersibles make sense.

>> No.3333683

So what are these rare earth metals used for? Since we've effectively increased the know, mine-able amount of these elements overnight by an order of magnitude, what does this imply for science? I look at the Wikipedia page for rare earth elements and see most uses involve lasers.

Pardon? I'm not sure what I've said that could be reasonably construed as idiotic.

If you're saying this because I've offended you at some point in the past, I apologize. And if you're just venting at me because something else happened to you recently that has put you in a bad mood, I certainly hope your luck improves.

Sup Richard. And yeah, seconding the investment advice. Everyone's going to need rare earths, and the first corporation to establish itself in the deep will become richer than the king of popes.

It's really the same rationale behind mining asteroids, but closer to home with a near term payoff and using subsea technology. I like to think of the ocean as the tutorial level before we conquer space, in that respect.

Why would engineers create robots that eliminate the need to build long, rigid living structures in which sweaty shirtless men coexist in cramped conditions?
