Did You Know:
Tellurium is a critical element recovered primarily as a byproduct of bulk copper mining. Its scarcity is astonishing:
It takes the equivalent of nearly 30 commercial dump trucks of copper ore to yield just 500 grams of pure Tellurium.
This rarity and technological importance—especially in solar and electronics—have prompted countries like China to implement export restrictions.
In fact, Tellurium is over 8 times rarer than gold in the Earth's crust.
