The Ultra-Pure, Super-Secret Sand That Makes Your Phone Possible (wired.com) 160

Posted by msmash from the closer-look dept.
The processor that makes your laptop or cell phone work was fabricated using quartz from this obscure Appalachian backwater. From a report: Alex Glover is a recently retired geologist who has spent decades hunting for valuable minerals in the hillsides and hollows of the Appalachian Mountains that surround Spruce Pine, North Carolina. Spruce Pine is not a wealthy place. Its downtown consists of a somnambulant train station across the street from a couple of blocks of two-story brick buildings, including a long-closed movie theater and several empty storefronts. The wooded mountains surrounding it, though, are rich in all kinds of desirable rocks, some valued for their industrial uses, some for their pure prettiness. But it's the mineral in Glover's bag -- snowy white grains, soft as powdered sugar -- that is by far the most important these days. It's quartz, but not just any quartz. Spruce Pine, it turns out, is the source of the purest natural quartz -- a species of pristine sand -- ever found on Earth.

This ultra-elite deposit of silicon dioxide particles plays a key role in manufacturing the silicon used to make computer chips. In fact, there's an excellent chance the chip that makes your laptop or cell phone work was made using sand from this obscure Appalachian backwater. "It's a billion-dollar industry here," Glover says with a hooting laugh. "Can't tell by driving through here. You'd never know it." In the 21st century, sand has become more important than ever, and in more ways than ever. Most of the world's sand grains are composed of quartz, which is a form of silicon dioxide, also known as silica. High-purity silicon dioxide particles are the essential raw materials from which we make computer chips, fiber-optic cables, and other high-tech hardware -- the physical components on which the virtual world runs.

      According to Webster's then term backwater can mean, "isolated or backward place or condition." A glance at the map shows that Spruce Pine, North Carolina is indeed pretty isolated. Hope that makes you feel a bit less hurt.

      If the back waters were to stop shipping all resources they have to big cities. Lets see. That would be food, water, any and all minerals, timber, and anything else that big cities need but will never get without the backwaters. I bet the elites would show more respect.

        If backwaters stopped selling their stuff to rich cities, their quality of life would collapse. They might have enough food to sustain themselves but that's about it. They won't have electricity, air-conditioning, tractors, pesticides, paved roads, cars, any variety in their diet at all, and life will be so damn boring when the only entertainment is some banjo player. Hell, they wouldn't even have banjos since those came from africa.

      • That'll fix'em. And they can keep their highfalutin phones and movies and stuff.

      • And those backwaters will then learn about all the funding the big cities sent to build and maintain the infrastructure in the backwaters.

    • Find somewhere with finer sand. The Redneck Riviera^W^W "Emerald Coast" of Florida has very fine white sand. Still irritant if you rub yourself in it, but one hope's you're smarter than that. It's nowhere near as coarse or rough as sand most places. Plus, it squeaks when you walk on it.
    • Fumed silica is powdered sand. It has a number of uses, one common one is for fillers in other solidifying liquids such as rubber, glue and paint. 'Food-safe' (sterile) fumed silica is a common food ingredient/thickener. You can buy bags of it on ebay.

      Fumed silica bounces. If you hit a bag of fumed silica with your hand, you can feel it vibrate after for a bit, as if it is rubber.

      Oh--and also it can kill you (if you breathe it) ... but then again, what fun stuff doesn't do that?

      It's a classic case of using the Latinate instead of the far-preferable Anglo-Saxon option. In this case, "sleepy." (Unless a train station can somehow sleep walk.)

      Maybe the writer just over-cogitated the word choice.

      • ambulant = walk, any dictionary that simplifies that to sleepy shows it's youth

        • ambulant = walk, any dictionary that simplifies that to sleepy shows it's youth

          You're right, it isn't a straight substitution. I still think the author failed at a clever replacement for "sleepy," given the context. The imagery just makes no sense.

      I thought it was a great word choice, nice poetic imagery. Obviously the train station doesn't sleepwalk (just as a "sleepy" station doesn't drowse), but the word evokes an image of someone going through the motions while not actually awake/alert. Plus the word has a nice rhythm and sound to it. I liked it.

      Start with TFA, which gives an overview. Basically, purity is measured by how many (expensive, trade secret) physical and chemical processes you have to run the sand through until you wind up with just the desired material. Probably not something you are going to do as a hobby.

    This is a setup for telling us we are going to run out of sand. Yes like we will run out of aluminum (which literally the most abundant metal in the Earth surface/crust), or water. All it means is an extra purification step. Without an ideal ore it just means we need to do extra purification steps .. like for example desalinating sea water or building pipelines into desert areas. If we ran out of this quartz we can use sand from somewhere else .. it may cost more in terms of energy to purify it thats all. Use solar or nuclear fusion (eventually) or something.

      • The running out of sand bit actually isn't a tin hat talking point, it just needs more specific wording. The problem is that production of concrete uses up a lot of sand, and in particular sand that is rough around the edges. When talking about running out of sand people typically point to the worlds immense deserts and laugh. However the sands in the deserts have been weathered to the point that they aren't very good for making concrete. In some countries there is actually a problem with illegal dredging o

    A couple of years ago some fat cats in Charlotte tried to buy land to dig a sand mine here near my town of Red Springs NC. It didn't happen: town fathers were rightfully suspicious because of several misleading statements from the purchasers ("We want to build big mansions!"), the history of total environmental disaster aftermaths in nearby counties from similar sand mines, etc.

    The word finally was that they wanted the sand (particularly good stuff for top-end glass, they were now saying), and of course they'd clean everything up.

    Riiii-ight. Still, one wonders if our sand is as good as that pure quartz stuff up in the mountains. Numerous sand pits around here, part of our ancient history as a shallow sea bottom, but none particularly distinguished.
