At present, Straton Maden has substantial feldspar reserves, logistical mining operations and commercial teams based in the West Aegean region of Turkey. Straton has total reserves of 20 million tons in its licensed field of operation and currently produces 300,000 tons per annum.

In 2013, Global Investment Holdings Group invested in the feldspar sector with the acquisition of Straton Maden. Straton Maden aims to become a leading player in the global feldspar market, following GIH’s other successful investments in the ports, power, gas, real estate and finance industries.

Feldspar is extensively used in the glass, ceramics and paint industries. Known for its high quality, low iron and titanium content, sodium feldspar in Turkey is mainly extracted in Manisa, Kütahya, Aydın and Muğla provinces. With overall reserves of 250 million tons, Turkey holds 15% of the world’s total known feldspar resources.Turkey is already the world leader in the production of feldspar mining in the amount of 6 million tons annually.

Today, Turkey is the world leader in feldspar mining, with annual production exceeding 6 million tons. Around 80% of Turkey’s annual production is exported.Key export markets include Spain, Italy, Russia, Lebanon, Egypt, Germany, Poland, Israel, Algeria, Romania, and Asia.

Currently, Straton Maden boasts significant feldspar reserves, logistical mining operations and commercial teams based in Turkey’s Western Aegean region. Straton has total reserves of 20 million tons in its licensed field of operation. The company’s annual production capacity totals about 750,000 tons. Eighty percent of Straton’s production is exported to Italy, Spain, Egypt, UAE and various Asian markets for use in the glass and ceramics industries.

Straton Maden aims to extract feldspar in the most efficient and environmentally responsible way, while producing higher value feldspar products. To this end, Straton Maden completed a capital investment program that established new separation and enrichment facilities while expanding existing production capacity. Thanks to these new facilities, Straton Maden substantially increased its production and feldspar sales volume. It also diversified its customer base by entering new export markets. Now, the company is one of the leading players in the sector.

European Standards

Straton Maden boasts a well-established customer base. The company ensures that every product offered fully meets European market quality and service standards. Following its acquisition by Global Investment Holdings, Straton continues to add significant value to the Turkish economy by exporting natural resources. After completing capital investments back in 2016, Straton Maden continues boosting production, product quality and sales volumes by deploying world-class advanced technologies.

Today, demand is rising for feldspar across various industries. Feldspar’s use increases the impermeability and durability of final products in the ceramics industry, facilitating higher yields. The increased use of glass in packaging – in response to the detrimental effects of plastics on the environment and human health – has also boosted demand for feldspar, which is used for insulation and clarity in the glass industry.
