Spodumene has a theoretical Li 2 O content of 8.03%. Due to its high lithium content, spodumene is considered the most important lithium ore mineral. A typical run of mine ore can contain 1-2% Li2O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li2O (75% – 87% spodumene).

Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes.
