- OYAK Mining Metallurgy ;
Etibank was founded on 14 June 1935 to operate and use Turkey's underground resources. Etibank was to produce metals, industrial raw materials and energy for the industry, and also perform banking activities to raise the capital necessary for these projects. Etibank started iron ore mining and iron-steel production activities when it first extracted iron ore in Divriği in 1938. Iron ore mining was transferred to the Turkish Iron and Steel Enterprise in 1955, coal mining was transferred to the Turkish Coal Enterprise in 1957 and the power generation and transmission facilities were transferred to the Turkish Electricity Administration in 1970.
Founded on 3 April 1937, this enterprise previously operated under the title "Administration of Iron and Steel Factories" and was affiliated to Sümerbank until 13 May 1955.
Upon its enlargement with the addition of various units of the Iron and Steel Enterprise, the Administration was separated from Sümerbank and became an independent state economic enterprise under Law No. 6559 dated 13 May 1955, and its name was changed to "General Directorate of the Iron and Steel Enterprise of Turkey." Incorporating, on 21 June 1955, the Divriği Iron Mines, which was an Etibank company, the enterprise trained experienced in-house installation experts and led the establishment of heavy industry and the İskenderun Iron and Steel Factory, the third iron-steel factory of Turkey.
Until 1986, the ore produced at Divriği was sent to sintering facilities or blast furnaces directly as weighting agents after being broken and sifted, without any enrichment process being applied. In order to take advantage of new technologies, the establishment of the iron-ore enrichment and pelleting facilities in Divriği was planned following the feasibility study performed in 1972. The ore enrichment facility was completed in 1978 and the pelleting facility in 1979, but these facilities could only be commissioned in 1985 and 1986 due to the delay in the construction of auxiliary units.
The title of the Divriği Hekimhan Madenleri Sanayi ve Ticaret A.Ş, an Ereğli Demir ve Çelik Fabrikaları T.A.Ş. subsidiary privatized by the Privatization Administration in 1987, was changed to Erdemir Madencilik Sanayi ve Ticaret A.Ş.
The privatization of Erdemir was completed on 27 February 2006 with the transfer of public shares to OYAK Group. Thus, Erdemir Maden, an Erdemir Group company, became an OYAK affiliate.
Deciding to systematize its occupational health and safety efforts in 2007, Erdemir Maden obtained the OHSAS 18001 Occupational Health and Safety Management System certificate in December 2009. Holding an OHSAS certificate since 2009, Erdemir Maden broke new ground in the iron ore mining industry with this certificate.
The underground iron mine investment, which started in October 2009 in the village Ekinbaşı, district of Divriği in Sivas, was completed in September 2011 (in just 23.5 months). While the remaining reserves in the mines that meet the pelleting facility's need for ore are 9 million tons, the raw material processed by the pelleting facility increased to 14.4 million tons with an additional workable reserve of 5.4 million tons upon the commissioning of the Ekinbaşı Mine.
The total budgeted investment of the Ekinbaşı Mine is TL 33.6 million, and the investment as a whole, including preparation, development costs and machinery and equipment purchases, was TL 33.4 million.
