World Boron Reserves
Boron was discovered by Joseph Gay-Lussac and Louis Thénard, French chemists, and independently by Sir Humphry Davy, a British chemist, in 1808
Boron is a hard, brittle semi_metallic element.
Chemical Symbol : B
Atomic number : 5
Atomic weight : 10.81
Melting Point : 2348 K
Boiling Point : 4273 K
Boron does not occur in nature as free element, occurs in nature as a mineral with associated clay and other impurities.There are over 200 naturally occurring boron containing minerals but the most commercially important and frequently traded minerals (salts, known as borates) are tincal, colemanite, ulexite and kernite . These ores can be refined into a pure chemical compounds of commercial importance are:
Boric acid H3BO3
Anhydrous boric acid B2O3
Anhydrous borax Na2B4O7
Borax pentahydrate Na2B4O7.5H2O
Borax decahydrate Na2B4O7.10H2O
Sodium Perborate NaBO3.H2O
Some commercially important boron minerals
Turkey is the largest producer of boron ore in the world. İmportant boron minerals of Turkey's are tincal, colemanite and ulexite. Boron minerals contain different amount of B2O3 in their structures. The important factor for industrial application of boron minerals are B2O3 content, so they can replace each other in use . This means that one boron mineral can be trade competitor the other one.
Boron minerals can be used in some sectors in the industry as crude minerals. In general, their applications after refining and end-products are wider than crude ones. Borates find use in a different sectors, however the principal markets are: Glass,ceramics and frit, detergents and soaps, agriculture.
In the world, Turkey, USA and Russia have the important boron mines. In terms of total reserve basis, Turkey has a share of %72.20, the other important country USA is %6.8.
Total world boron reserves on the basis of B2O3 content are 369 million tons proven. 807 million tones probable and possible, as a total of 1,176 million tons. With a share of %72.20, Turkey has a total boron reserves of 851 million tons on the basis of B2O3 content .
