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.

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)

High-purity quartz [which is used across the solar manufacturing sector and also for computer chips]—most of it comes from the US.

[Ultra-pure quartz] is actually one example where there’ve been a lot of joint public-private efforts to develop more ultra-pure quartz capacity in China. They’re investing in domestic production because that’s one sector where North America dominates current production. [Two American companies in North Carolina] produce like 180,000 tons of ultra-pure quartz a year; [Jiangsu Pacific Quartz Products, a Chinese company] is scaling up [its capacity] this year from 5,000 to 20,000 tons; and that’s basically all of the global production.

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.
