- oportunityastro 4y agoIt is nothing to do with anything. Copper is relatively abundant by this measure, but almost everyone who I know who has a view on copper see the future supply situation as terrible. There is politics, financial cycles, actual site economics...I mean the US right now is the perfect example of this, centuries of discovered natural gas reserves that is proven economic to take out of the ground, and natural gas is skyrocketing...it isn't that simple.
- philipkglass 4y agoThat's exactly what makes most of the rare earth elements "rare": they are common in the Earth's crust but rarely concentrated into easily mined deposits. Neodymium and praseodymium are also more common than tin but significantly more costly than tin because they don't form ore bodies like tin does under geochemical influences. https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth...
