I legit can't tell if this is sarcasm but if it is, A+
"They contain all kinds of things I can't name
So one of the issues is that many of them are trade secrets that are as closely guarded as nuclear codes...
Knew a guy from school who went to work for a chipmaker.
He had to get a security clearance just slightly less intense than you need working for the CIA or NSA.
IIRC, it was a year-and-half process, just to get an internship (he eventually got a FT job there, but we've kind of lost touch, given that I'm kind of a nutjob)
I can name lots of them though:
Germanium
Import Sources (2019–22):1, 6 Germanium metal: China, 54%; Belgium, 30%; Germany, 8%; Russia, 6%; and other, 2%. Germanium dioxide: Belgium, 47%; Canada, 46%; and other, 7%. Combined total: Belgium, 39%; China, 26%;
Copper
Chile leads with 19% of the world's reserves, followed by Peru with 12%, Australia with 10%, and Russia and Congo each hold 8%. Mexico and the United States each account for 5%
Silicon
In spite of the fact that sand (lots of silicon) is abundant, extremely high purity sources of silicon needed for advanced fabrication are quite rare:
In 2023 Silicon,
99.99% pure were the world's 796th most traded product (out of 4,644). In 2023, the top exporters of Silicon, >99.99% pure were Germany ($1.5B), United States ($1.37B), Malaysia ($637M), Japan ($384M), and China ($291M).
Gallium
China produces around 60% of the world's germanium, according to European industry association Critical Raw Materials Alliance (CRMA), with the rest coming from Canada, Finland, Russia and the United States.
Aluminum
Much aluminum is recycled (the world's most recyclable metal), but new aluminum is produced from Bauxite.
Australia 98,000 3,500,000
Guinea 97,000 7,400,000
China 93,000 710,000
Brazil 31,000 2,700,000
India 23,000 650,000
Indonesia 20,000 1,000,000
Boron
Turkey 948,712 73,4
Russia 100,000 7.7
USA 80,0006 .2
Could go on, but too long already.
You're welcome.
