Boron is an element which is widespread in the rocks and water on the surface of the earth. The boron content of soil which is generally on average between 10-20 ppm is found in high concentration in the Western regions of the USA and in the area between the Mediterranean and Kazakhstan.

Boron minerals are natural compounds which contain different proportions of boric oxide (B2O3) in their structures. Boron minerals commonly found in Turkey are tinkal, colemanite and ulexite. These minerals are primarily enriched by subjecting to a physical process, , and then converted into various chemical boron compounds by refining.

As well as boron is consumed mostly in the form of boron chemicals, it can also be consumed directly as concentrated boron products. Boron compounds are used in many areas such as glass industry, agriculture, chemical and detergents sector, ceramic and polymeric materials, metallurgy, nano-technologies, automotive and energy sectors, electronics and communications sectors, space and aircraft vehicles, nuclear applications, military vehicles,fuels, construction. However, 84% of the boron products consumed in 2015 was used in the glass (insulation type fiberglass, textile-type fiberglass, borosilicate glass and glass panels), ceramic-frit ,agriculture and detergent-cleaning industry.

The country that produces the highest amount of boron compounds is Turkey in order to has the largest reserves of boron in the World.

The most important boron reserves other than Turkey, are located in the USA, Russia and South America. Turkey has a total of 3,3 gigaton of boron reserves, which equates to 74% of the total world reserves, and puts it in first place in this respect.

Within the scope of the Boron Master Project, which was put into operation with the protocol entered into by the General Directorate of Mineral Research Exploration and Eti Maden, in 2002, explorations were carried out between 2002 – 2013, and as a result, our boron reserves, which amounted to 2 gigaton, with a B2O3 content of between 24-35%, were increased by 1,3 billion to 3,3 gigaton. The reserve development endeavours are still ongoing. In the same context, Bigadic Master Project (BİGMAP) is carried out. The objectives of this project are to meet the raw material needs of the new facility, to ensure the sustainability of mining operations and to plan new mines by reassessing the potential of the Bigadiç borate basin. With this Project 28.021 meters of drilling was carried out in 110 locations by the end of 2015.


All of the known boron deposites within our country are located in Western Anatolia, specifically; Eskişehir-Kırka, Kütahya-Emet, Bursa-Kestelek and Balıkesir- Bigadiç.

The consumption of boron products throughout the world is nearly 4 megaton . Approximately 50% of world boron demand in 2015 is met by Eti Maden.

Eti Maden who carries out the production of chemical boron compounds became the world leader in the sector in 2005 with its wide range of products. Eti Maden’s production capacity is 2,2 megaton . Eti Maden produced 436.000 tonnes of chemical boron compounds in 2002, and this rose to 1,83 megaton in 2016.

In 2016, 1,78 megaton of boron was sold by Eti Maden – an equivalent of 713 million US Dollars. That is to say, 96% of Eti Maden’s sales revenues came from export revenues.
