In the 1820s, massive deposits of platinum were found in the Ural Mountains. How did the Russian government use this surplus of metal between 1828 and 1845?
The Russian government faced a unique problem: they had a surplus of a "precious" metal that was nearly impossible to melt and had very little industrial use at the time.

High stability and low chemical reactivity does not react with oxygen or water.
Why does Platinum have no biological role?
It is a noble metal and they resist chemical reactions.
