Kırka has 3 million tons of tincal production per year by open pit mining.
In this facility, tincal is transformed into value added boron products such as borax pentahydrate, borax decahydrate, anhydrous borax, calcined tincal and also natural cleaning product.

These boron products are essential ingredients of various products such as fertilizer, fire extinguisher, adhesive, agrochemical, bleach, soap, insulating glass wool, metallurgical welding and textile paint.

In this facility, colemanite is transformed to boric acid. Boric acid plays an active role in , LCD screen eye, ear, skin treatment, insecticide production, fibreglass, prexy glass production and flame-proof clothing.


Bandırma facility transforms the tincal and colemanite ores extracted from Kırka, Emet and Bigadic sites to high value-added, quality and sustainable boron products namely boric Acid, borax decahydrate/borax pentahydrate, ground colemanite, anhydrous borax, disodium octaborate tetrahydrate (DOT), zinc borate and boron oxide (amorphous and glassy).

Bandırma facility, is one of the most important boron production centres of Turkey, with 400.000 tons of boron production and with its port facilities where more than 900.000 of boron products exported to more than 100 countries per year.


Bigadiç facility transforms boron minerals excavated from Bigadiç mines, to high value natural products with its vision of high quality. Along with the concentrated boron mineral, Bigadiç facility is also producing the world leading natural product “ground colemanite” which is only available in Eti Mine product portfolio.

Ground colemanite and ulexite are mostly used in agriculture and medicine. Concentrated colemanite and ulexite are used in heat insulation, sound insulation, ceramics, metallurgy, slag production, glass and glass fibre production.

Bigadiç facility is supporting its sense of quality with strong references with quality, energy, environment, occupational health and safety management system and accredited laboratory certificates.
