Salar de Uyuni is the world’s largest salt flat. It is located in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters above the mean sea level. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. It contains 50 to 70% of the world’s lithium reserves, which has yet to be extracted.
