The Sinter Plant receives, stores arriving raw materials and additions, as well as prepares those physically and metallurgically. 12 bunkers and 2 lime powder silos can be used for storing charge components. The charge fed on the sintering strand are composed of various ores, ore substitutes and fluxes, return material, as well as coke powder serving as fuel. The optimum grain size of the charge to be processed on the sintering strand is between 1 and 8 mm. As this grain size is relatively rare or very expensive, fine grained materials have to be prepared to have a condition that can be processed, which operation is called charge preparation. Charge preparation is a pelleting process, during which micro-grained parts stick to each other or to greater grained parts as an effect of water and binding material (burnt lime) charging and rolling movement generated in mixing drums.

Ores are metallurgically prepared on 2 pieces of Dwight-Lloyd travelling grated agglomerating plant, the so-called sintering strand. Sinter or agglomerated ore is produced by this method, a material with such physical and chemical properties that are more favourable from the point of view of processing in the blast furnace. Production capacity of sintering strands is 1,000,000 tons/year.

Ore Dressing Plant and Agglomerating Plant started operation in 1955, respectively in 1956.
