Ulexite

The Mineral ULEXITE
Chemistry: NaCaB5O6(OH)6-5H2O, Hydrated Sodium Calcium Borate Hydroxide
Class: Carbonates
Subclass: Borates
ULEXITE USES:
Agriculture field: Because of it's  properties, ulexite gets great results on agriculture as a good component for making different micronutrients and fertilizers.
Talking about agriculture, ulexite can offer it's goodness both products for microfoliar aplications and fertilizers to soil aplications.
Fries: Calcined ulexite is also used to make fries not only to ceramic industry but also for fiberglass industry.
Boric acid and borax production: Ulexite is also a necessary element to make other products related to borates family. As for example:
To make borax (decahydrate borax, pentahydrate borax or anhydrous borax) or to make boric acid

Ulexite, like other borates, is a structurally complex mineral. The basic structure of ulexite contains chains of sodium, water and hydroxide octahedrons linked in endless chains. The chains are linked together by calcium, water, hydroxide and oxygen polyhedra and massive boron units. The basic boron unit has a formula of B5O6(OH)6 and a charge of negative three (-3). It is composed of three borate tetrahedrons and two borate triangular groups.
Ulexite is found with the mineral borax and is directly deposited in arid regions from the evaporation of water in intermittent lakes called playas. The playas form only during rainy seasons due to runoff from nearby mountains. The runoff is rich in the element boron and is highly concentrated by evaporation in the arid climate. Eventually the concentration is so great that crystals of ulexite, borax and other boron minerals form and accumulate to great thickness.

PHYSICAL CHARACTERISTICS:
Color is white or gray to colorless.
Luster is silky.
Transparency crystals are transparent to translucent.
Crystal System is triclinic; bar 1
Crystal Habits include tufts of acicular crystals called "cotton balls". Also as vein-like masses of parallel fibrous crystals.
Cleavage is perfect in one direction.
Fracture is fibrous.
Hardness is 2 (softer than a fingernail)
Specific Gravity is approximately 1.97 (very low density)
Streak is white.
Associated Minerals are borax, colemanite, hydroboracite and other borate minerals.
Other Characteristics: similar borate minerals have an alkaline taste, while ulexite is tasteless.
Notable Occurrences include several localities in California and Nevada, USA; Uyuni Potosi Bolivia, Tarapaca, Chile and Kazakhstan.
Best Field Indicators are crystal habit, associations, locality, density, unique optical property, and hardness.

Nature salt (Uyuni lake)
( raw materials salt)

Uyuni salt lake is the biggest salt lake in the world. Uyuni is settled 3650m highland above sea level and boarderd of Chili. Where is windy and shiny weather conditions.
Undere these hard conditions make wondereful salt in the summit of the Andes.

Salar de Uyuni. It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, 3,650 meters high. The major minerals found in the salar are halite and gypsum.

Salar de Uyuni is estimated to contain 10 billion tons of salt, of which less than 25,000 tons is extracted annually.
It is also a significant tourist destination; highlights include a salt hotel and several so-called islands.
If the water is unable to drain into the ground, it remains on the surface until it evaporates, leaving behind whatever minerals were dissolved.
Over thousands of years, the minerals (usually salts) accumulate on the surface.
