important lithium ore mineral. A typical run of mine ore can contain 12% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 67% Li 2 O (75% 87% spodumene). Higher grade concentrates with % Li 2 O and low iron content are used in ceramics and more demanding industries.
