Lithium (chemical symbol: Li) is the lightest of all metals. It does not occur as a pure element in nature, but is contained within stable minerals in a range of hard rock types or in solution in brine bodies within salt lakes, in sea water or geothermal brines. The contained concentration of lithium is generally low and there are only a limited number of known resources where lithium can be economically extracted.
