Lithium is found in very low concentration in igneous rocks. The largest concentrations of lithium-containing minerals are found in granitic pegmatites. The most important of these minerals are spodumene (Li 2 O, Al 2 O 3. 4SiO 2) and petalite (Li 2 O, Al 2 O 3. 8SiO 2). Spodumene has a theoretical Li2O content of 8.03%. Due to its high lithium ...
