Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.
Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --
-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--
-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --
It also totally shut down the only supply for high quality quartz in the world. Like literally every electronic device that requires a silicon chip is dependent on those 2 mines in Spruce Pine.
It's wild how so much of the worlds critical raw material is still extracted in the most chronically impoverished parts of Appalachia.
I legitimately had no clue
Learning more about economics and media over the years has made me realize how much of "business news" in the west is just bourgeois mouthpieces conspiring to bury unflattering stories that might scare the markets and hurt their owners' bottom lines
Like that should be pretty obvious in retrospect looking at how mass media in the west is funded and who owns and invests in it as a material analysis, but it's shocking how thoroughly "huge example of how fucked (aspect of American economy) is" stories get relegated to brief passing mentions if not completely buried and totally verboten to report

I need to brush up on my Lenin, it's amazing how succinct and on the money he was about everything more than a century ago
first learning about appalachian mining towns in the "good old days" before they were left to deteriorate was quite an experience. It was pretty much just a system of mineral-serfdom. The mining companies owned literally everything, including all the stores (which were basically one megastore), and they wouldn't even pay the workers real money. They'd pay the workers in scrip, ie fake money that could only be used in the stores they owned (LITERALLY MONOPOLY MONEY). So even if people wanted to move, they had no way to ever save up to because they weren't actually being paid in real wages. No wonder appalachia was so revolutionary. The ruling class deserve(d/s) worse than the coal wars tbh
does china really not have its own source?
They've identified it as a critical resource (as has a number of other countries - Australia has a few startups to commence mining it)

It is possible to refine lower quality quartz into higher quality quartz but it is very energy intensive.
The entire global market is only $1 billion so that's part of the reason why there hasn't been much competition.
Can't they make high quality quartz in a lab like diamonds and sapphires?
It's possible but difficult - I believe there's research underway on how to better synthesise extremely high purity silicon dioxide (99.9999%) for sub-3nm semiconductors. Nothing at the volume required.
Here is an existing purification method for high purity quartz (99.98%)
You can also see that some elements are particularly troublesome to remove - lithium, aluminium and titanium.
Thank you for the information! I have another question if you don't mind.
If the global market is only 1B why should anyone worry about this? I'm getting the impression that silicone chips aren't that important and might even have better substitutions. Am I wrong to think this way?
It would be an issue if someone nuked Spruce Pine as it would take a reasonable amount of time to survey and prepare mining infrastructure for other sites.
High purity quartz is very important but there's probably enough existing inventory for the mines to commence operating again (and there's still all the stuff in the refining and purification chain).
It's just concentrated in NC because it's relatively cheap and low volume - $5 a kg, similar to the price of zinc except that zinc mining and demand volumes are ~100 times higher. They have the biggest known deposit so there's no point to develop your own mining and refining industry unless you think your country will be cut off.
Or another example, most of the world's cobalt is mined in the Democratic Republic of the Congo, and there would be huge supply chain disruptions if you nuked the DRC - but that doesn't mean that cobalt has little value. Of course in they scenario, other mines would open (or reopen, in the case of Australia which was the primary cobalt producer until the ~late 90s).
They are pretty different:
you telling me that i can buy standard-purity high-purity quartz? thats fucked up
Wait what? That is actually astonishing
I was just about to comment on the quartz mining. The rail lines have been destroyed as well, so they can’t access what has been mined. Plus, a lot of that ended up washed away in the floods, it’s why some of the flood deposits look like straight up beach sand.
