The dystopian lake filled by the world’s tech lust

Now it's back on line, after a huge rebuild.[1] It wasn't easy to satisfy California environmental controls, but they did it. Even the Sierra Club is reasonably satisfied.[2] Rather than tailings ponds, they have a large back-end processing operation which gets the water out of the tailings. They can then reuse the water (a big deal during the drought), and they get a solid waste material out, which is essentially what was in the ground to begin with, minus the good stuff.
A few years ago, China tried cranking up the export price of rare earths, and refused to export them to Japan at all. So users of rare earths came up with alternatives, and production restarted in the US, Australia, and Canada. Rare earths aren't all that rare worldwide, it turns out. With demand down and production up, the price tanked.
Molycorp, which owns the US mine, is having terrible financing problems, but the mine and all the associated gear are up and running, producing about 4,000 metric tons a year of rare earth materials. Rare earth supply is now mostly a solved problem. China's mining operation remains a mess, but that's not inherent in rare earth mining any more.

They are called rare because, (almost) whatever hand of earth or rock you grab, they are rare within that hand.
some of them aren't rare in the "there isn't much of it" sense at all. For example, http://en.m.wikipedia.org/wiki/Rare_earth_element claims Cerium is the 25th most abundant element in the Earth's crust.
Interesting tidbit: that page also shows that four rare earths are named after a single village in Sweden (Ytterbium, Terbium, Erbium, and Yttrium)
Three times the background radiation is hardly noteworthy. It would have been much more interesting to know what they found in the waste water. Sulphuric and nitric acid?
It would also be interesting to know the air quality in that city as well.

What exactly did the article define as the background? The ambient conditions of the laboratory?
Also, it is not just the uranium in the granite that is responsible for the radiation. Thorium and potassium are significant as well.
Separately, I'm not sure I like his usage of "dystopian."
You can tell because of all the presumptions he makes and suggestions that he never backs up with fact.
But I would disagree that even here on this forum a lot of people are really aware of the true environmental impact of tech manufacturing. We've pushed most of that off to remote regions of asia that nobody in the west regularly sees or worries about. We just see the end product, be it finished hybrid or electric vehicles, wind turbines, or the latest gadget conspicuously packaged in recycled paperboard.
So basically along with really low prices, the supplier is bundling a free absolution of our guilts along with their pollution! Ain't that grand.
In this case, the supplier should be required to put up collateral or purchase some kind of cleanup insurance for cleanup. i.e. there needs to be a basic regulation from the government on land granted to mining.
Earth is gigantic. This lake takes up maybe, what, .00001% of surface area? And is even less consequential by volume.
The intriguing thing about both neodymium and cerium is that while they’re
called rare earth minerals, they're actually fairly common. Neodymium is no
rarer than copper or nickel and quite evenly distributed throughout the
world’s crust. While China produces 90% of the global market’s neodymium,
only 30% of the world’s deposits are located there. Arguably, what makes it,
and cerium, scarce enough to be profitable are the hugely hazardous and
toxic process needed to extract them from ore and to refine them into usable
products. For example, cerium is extracted by crushing mineral mixtures and
dissolving them in sulphuric and nitric acid, and this has to be done on a
huge industrial scale, resulting in a vast amount of poisonous waste as a
byproduct. It could be argued that China’s dominance of the rare earth
market is less about geology and far more about the country’s willingness to
take an environmental hit that other nations shy away from.
ie the rare earths minerals aren't rare, just very toxic to extractThis situation reminds me of something I read a few years ago - an interview with noted (?) right-wing polemicist P. J. O'Rourke, at the time apparentlny on the merry-go-round promoting his then-new book: http://rightwingnews.com/interviews/the-p-j-orourke-intervie...
Part of the bit that stuck in my mind:
[...] the exports, that’s real stuff, and you’re giving it away in
favor of gold. He [Adam Smith] said imports are the good thing.
Imports are when you’re getting something you like. You’re getting
French wine. You’re getting American tobacco. You’re getting furs
from Russia, getting whatever they were getting back in those
days. He said exports are the way you pay for those imports. So
imports are Christmas morning. Exports are January’s Visa bill.
(Search for that quote. His whole answer to that particular question is quite interesting.)I think of this every time I read anything about acres of toxic sludge and skies full of clouds of carcinogens. I don't quite share O'Rourke's apparent glee at how fools will sweat blood to extract raw materials, actual honest-to-god assets, and then swap them for mere money, money whose ultimate value is entirely under somebody else's control... but I do wonder what the hell they are thinking, and what sort of a deal they think they are getting. Because from my perspective, it looks like they're getting shafted.
I find this sort of first-person journalism interesting, but not terribly credible. It lacks perspective or insight. Not a single local is quoted.
Recycling is hard. Particularly in comparison to processing ore. When reclaiming desirable metals from electronics you are faced with an extremely heterogeneous starting material - sheet metal cases, fasteners, glass, all sorts of plastics, fibreglass circuit boards, insulated wire, etc.
In contrast, REE ore is a relatively homogeneous mix of silicates, oxides and carbonates. All are inorganic, and have sufficiently similar properties that the bulk material can be crushed then milled to a fine powder ready for processing. If your resource is competently characterised, you will also know to a reasonable degree the REE content to expect per tonne of ore.
What is the Nd content of one tonne of e-waste? Hell, what is the composition of 1 tonne of e-waste? How do you even assay e-waste?
