All CCM products are characterized by medium to high MgO purity, low level of impurities and undesirable substances, low SO3 content and low trace elements/heavy metals. In addition, the possibility to mill in various grain sizes (up to -45μm) & the use of natural gas during calcination enables AMK to commercialize its products in a wide range of high demanding applications, such as production of special magnesium compounds, rubber & plastics, catalysts, special feed/food additives, fuel additives, pigments & fillers, electrical grade fused magnesia (EGFM), refractory grade fused magnesia (RGFM), production of Al-Mg spinel, hydrometallurgy, petrochemical industry, leather tanning, construction – Sorel cement applications, agriculture. 

The company’s major deposits and production facilities are located in the Eskisehir area - Kümbet, Erenkoy - in the Central-Western part of Turkey. The deposits consist of three main concessions totaling 4.238,5 hectares with significant proven reserves. Mining of magnesite ore (cryptocrystalline type) is carried out open cast. The main factory is located at Kumbet and consists of 2 shaft & 1 rotary kilns with a combined calcination capacity of >32,000 tpy of CCM, post processing facilities (i.e. crushing, screening, magnetic separation, mixing, milling, packing, storage, forwarding), offices, laboratory - quality control, earthmoving equipment maintenance workshop. Assets also include four pre-beneficiation facilities at Aktepe, the main beneficiation plant in Erenkoy (crushing, washing, screening, magnetic separation, sorting) and the headquarters located in Istanbul.
