BORONANDBORONINTURKEY

slide5

A low-abundance element in both the solar systemandthe Earth's crust, boron is concentrated on Earth by the water-solubility of its more common naturally-occurring compounds, the borate minerals.

slide8

Industrially, very pure isolated boron is produced with difficulty, as boron tends to form refractory materials containing small amounts of carbon or other elements.

slide9

Boron is used mainly not as the element boron, but as compounds of boric oxide (B2O3)and boric acid (H3BO3).Most people have never seen elemental boron.

Boron does not appear on Earth in elemental form but is found combined in borax, boric acid, colemanite, kernite, ulexiteandborates.
slide47

They are both found in the Mojave Desert of California, but the largest borax deposits are in Central and Western Turkeyincluding the provinces of Eskişehir, Kütahya and Balıkesir.

slide49

The Turkish borate deposits in Western Anatoliaare located in five main districts: Bigadiç, Kestelek, Sultançayır, Emet and Kirka.

slide51
They formed in a lacustrine environment during periods of calc-alkaline volcanic activity in the Neogene.
slide52

There are differences between the different districts, but the borates are all generally enclosed withinlimestones and clays and are interbedded with layers of volcanic ash, limestone, marl and clays.

slide57

The main boron minerals are borax, colemanite, and ulexite, with the proportions of these minerals varying between the deposits. A large number of other borate minerals are found in the deposits, including pandermite, inyoite, meyerhofferite, tincalconite, kernite, hydroboracite, inderite, inderborite, kurnakovite, terrugite, veatchite-A, and tunnelite.

slide58

The boronin the deposites is assumed to be derived from leaching of the surrounding rocks by geothermal activity associated with local volcanism.

slide68

In order to utilize mining resources more effectively, the boron operation of Turkey has been transferred to Eti Mine by law and it consists the main activities of Eti Mine

slide70

It has been operating since 1967 in Bandırma county of Balıkesir. In order to transform boron minerals into high value added boron products, Borax Decahydrate, Borax Pentahydrate, BoricAcid, Sodium Perborate, (tetra+mono) and Boron Oxide are produced in the plant’s facilities and most of the production is exported. Besides, Sulphuric Acid is produced in 240.000tons/year capacity Sulphuric Acid Plant.The products of the other Boron Works are exported using the loading facilities present in Bandırma Boron and Acid Plants Works.

slide72

It is located in Kırka area of Seyitgazi county of Eskişehir. Concentrated tincal production in the plant where construction operations began in 1970, started in 1975 which is followed by theproduction of high value added boron products in the Boron Derivatives Plant in 1984.Raw tincal ore, excavated in the plant’s open pitmine, has been transformed into refined products (Etibor-48) in the plant’s facilities with 480.000 ton annual production capacity.

slide74

It has been active since 1958 in Emet county of Kütahya. In the open pit mines of Hisarcık and Espey, colemanite ore production with 28-30%B203 grade is 1.000.000 tons/year. In order to transform the ore into the refined boron products, Boric Acid is produced in the facilities with 100.000 tons annual capacity.

slide76

It is located in the Bigadiç county of Balıkesir. The plant where production activities began in 1976, has three open pit mines from which 800.000 tons/yearUlexite and Colemanite ores with 29-31% grade are produced.The raw ore mined from the plant’s own mines has been enriched into concentrated colemanite and concentrated ulexite in the 650.000 tons/year capacity concentrator facilites since 1980 and grinded into ground colemanite and ground ulexite in the 90.000 tons/year capacity grindingfacility since 1998.

slide78

It is situated in Kestelek village of Kemalpaşa county of Bursa province. Raw colemanite ore production in the plant’s open pit mine is 200.000 tons/year with 29%B203 grade. The produced ore is enriched in the 100.000 tons/year concentrator facility into concentrated colemanite.

Reserve

Eti Maden has 67% of the world boron reserve with its 883 million tonsB203boron reserve (This ratio is about 72% if approximate 102 million tonsB203 reserve of Satimola boron deposits located in Kazakhstan is not taken into account).
