Salar de Uyuni is estimated to contain 10 billion tonnes (9.8 billion long tons; 11 billion short tons) of salt, of which less than 25,000 t is extracted annually. Lithium is concentrated in the brine under the salt crust at a relatively high concentration of about 0.3%. The brine is a saturated solution of sodium chloride, lithium chloride, and magnesium chloride in water. During the wet season, Titicaca overflows and discharges into Poopó, which in turn, floods Salar De Coipasa and Salar de Uyuni.

Things to Know Before Choosing a Tour

Daytime can often feel pleasantly warm in the sun, but after it sets temperatures can easily plummet to around -10°C. If you’re booking a budget tour, expect there to be an additional cost.
