This high grade iron ore concentrates in form of slurry is transported to pellet plant through underground slurry pipeline. After receiving this slurry at pellet plant, the slurry is filtered and filtered cake is being used to produce iron ore pellets through indurating furnace of travelling grate technology.
A number of compressive tests were conducted on iron ore pellets obtained from the Samarco pelletizing plant located at Ponta Ubu, Brazil. These pellets are formed by disk pelletizing of a mixture consisting of hematite iron ore, (particle size less than 50 µm) water, and lime; they are hardened in a traveling-grate furnace and the nominal diameter
Pellets is one of the main iron ore raw materials in blast furance ironmaking and produced by iron ore with almost Fe 2 O 3, a little amount of waste and carbon under 1200°C temperature. Pellets as shown in Fig. 3 in experiments are 1/4 size of the real pellet particles (10–14 mm) and were created by LKAB in Sweden.
Vale is the world's biggest producer of iron ore and pellets, raw materials essential to the manufacture of steel. Iron ore is found in nature in the form of rocks, mixed with other elements.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Ore beneficiation then occurs in concentrators, where crushing, milling, desliming and flotation processes produce iron concentrate. The concentrate leaves the concentrators as slurry and is pumped through the slurry pipelines from the Germano facilities to the pellet plants in Ubu, Anchieta, where the slurry is processed into pellets.
A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
