Bauxite consists of aluminum iron oxide and hydroxide and minerals (such as boehmite, gibbsite, diasphore). It develops as a result of filtration and washing of rocks which consists of aluminum silicate concretes secondarily with rain under tropical conditions. They can be observed in green, brown, red and grey colors.
Bauxite hardness of which changes between 1-7 in Mohs scale, intensity of which changes between 2,5-4,5 gr/cm³ has an important role in world trade for being main mine on production of aluminum metal. Bauxite is also used frequently in cement, iron and steel, refractory and abrasive industry.
Known world Bauxite reserve is approximately 38 billion ton. Guinea has %23 of the world reserve with 8.6 billion tons, Australia has %21 with 7.9 billion tons, Vietnam has %14 with 5.4 billion tons and Brazil has biggest reserve with %7, 5.4 billion tons and rate.
Known bauxite reserve in Turkey is 68.910.000 tons according to MTA data. This number constitutes pretty little part of world reserve as 0,001.8. %90 of bauxite mined in world is used for production of aluminum and this increases in parallel with aluminum demand. Production of bauxite has reached 350 billion ton in the world since 2015.
Proved reserve in Demireller Mining A.Ş. bauxite areas is estimated as 8 billion tons, potential reserve is estimated as 16 billion tons.
Demireller Mining Chemical Analysis Laboratory went into action in 2010. Chemical analysis of various industrial ores particularly iron was started to be made as of the inclusion of XRF Chemical Analysis Device to the system in 2011.
Production has been made with surface mining method in our mines. The classification and processing of bauxite are performed according to the sizes demanded by the customers and approximately 4.000 ton bauxite is processed in crushing- screening facility located in Arslanköy-Mersin, approximately 2.000 ton bauxite is processed in crushing-screening facility located in Belen-Muğla and approximately 2.000 ton bauxite is processed in crushing-screening facility located in Mihalıççık-Eskişehir. Our products are shipped to the customers from three various ports according to customers demand after quality controlling in laboratory.
Besides making any production according to demand, generally production is made on granular size stated below:
0-10 mmAlumina cement raw material(CAC)
Cinder healer in high iron and steel kiln
Portland cement of additive raw materials in alumina production and abrasive industry.
Our bauxite is diasphore characterized and has chemical value range stated below. Chemical analysis changes according to granular size and place of production.
