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% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are

Australia and Chile are the world's largest producers of lithium.

Put simply, lithium from Australia comes from ore mining, while in Chile and Argentina lithium comes from salt deserts, so-called salars. The extraction of raw materials from salars functions as follows: lithium-containing saltwater from underground lakes is brought to the surface and evaporates in …
