Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl (Si2O 5) 2, lepidolite K (Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl (SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.
