How do you get corundum?

Answer 1

Corundum is the mineral/crystalline form of Aluminium Oxide, and is mainly mined from metamorphic rocks such as schists, gneiss and marbles. Corundum can also be mined from pegmatites, seyenite and ultramafic intrusive rocks. The varying colouration of corundum is due to chemical impurities, ie, chromium present in the crystal will give it a red colour - hence the gemstone will be a ruby.

Answer 2

Corundum is typically mined from mineral deposits and extracted through traditional mining methods such as open-pit or underground mining. It can also be found in riverbeds or as a byproduct of processing other minerals like aluminum.
