Salar de Uyuni

Salar of Uyuni is the largest salt mine in the world. It is located in the department of Potosi in the southwest of Bolivia, near the crest of the Andes, at an altitude of 3650 meters above sea level, with 10 582 km² (4085 square miles).

In the center is a group of islets, the most important of all is the Isla del Pescado, which is characterized by its huge cactus and houses some services. You can hire excursions from the town of Uyuni, and there is also the possibility to go from the city of Atacama (in Chile) through the Andes mountain range.

The Salar of Uyuni is the largest continuous salt desert in the world, with an area of 12,000 km². The salt is distributed in 11 layers ranging from 2 to 10 meters thick. The salt is about 120 meters deep.

It is estimated that the Salar of Uyuni contains 10 billion tons, of which less than 25,000 tons are extracted annually.

Salar de Uyuni, contains very important compounds for basic and industrial chemistry. There are approximately 11 layers of salt, with thicknesses ranging from less than one meter to ten meters. The crust that is on the surface has a thickness of 10 meters. The depth of the salt is 120 meters, which is composed of layers of superimposed brine and lake mud. This brine is composed of lithium, boron, potassium, magnesium, carbonates (borax) and sodium sulfates. A very interesting mineral is the ulexite, the stone television. It is transparent and has the power to refract the image of what is below to the surface of the stone. This salt is considered the largest reserve of lithium, although it is very difficult to extract due to lack of water.
