Grok:
No, uranium is not scarce on Earth. It is a relatively common element in the Earth’s crust, ranking as the 48th most abundant element overall, with an average concentration of about 2.7 parts per million (or 0.00027%). This makes it roughly as abundant as tin or zinc and about 500 times more common than gold.
Economically viable ore concentrations for mining are much rarer. High grade deposits like those in Kazakhstan are rare and valuable to someone wanting to produce enriched or highly enriched uranium.
