Salar de Uyuni
Located in the Lithium Triangle, the Salar contains a large amount of sodium, potassium, lithium and magnesium (all in the chloride forms of NaCl, KCl, LiCl and MgCl2, respectively), as well as borax. With an estimated 9,000,000 t, Bolivia holds about 7% of the world's known lithium resources; most of those are in the Salar de Uyuni.
