The Story of Ore
-
01
Heart of Iron Ore
Iron ore is extracted using drilling and blasting methods, then crushed underground to a size of 170 mm.
02
Secondary Crushing
The 170 mm ore is transported via a 4,000-meter-long conveyor belt to secondary and tertiary crushing-screening facilities.
03
Blending Yard
The ore, reduced to 10 mm, is homogenized with ore from the Hasançelebi site in the blending yard.
04
Concentration Plant
The homogenized ore is transported to the concentration plant, where it undergoes dry separation for pre-enrichment and is ground to -75 microns. After wet magnetic separation, the concentrate is filtered to reduce moisture to 10% and sent to the pelletizing plant.
05
Pelletizing Plant
In the mixing unit, 1% bentonite is added as a binder to the concentrate. The mixture is then fed into balling drums to form green pellets, which are dried at 350°C, preheated at 1,050°C, and finally heated to 1,280°C in a rotary kiln.
06
Finished Product Storage
Pellets, as the raw material for steel, are sent to finished product storage silos for dispatch to İsdemir, Erdemir, and Kardemir.
07
Dispatch
The pellets stored here are transported by railway to integrated iron and steel plants.
