furnace use (BF-grade pellets) and those used to make DRI to feed an EAF. A "DR-grade" pellet typically has higher iron content and less silica, alumina and other gangue constituents than "BF-grade" pellets.
1.3 Charging the blast furnace/ BOS plant Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material)
Iron ore green balls are soft and easy to break. So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process.
It is the process of converting iron ore fines into 'uniformed sized iron ore pellets' that can be charged directly into a blast furnace. Fig 1 shows iron ore pellets. Fig 1 Iron ore pellets There are several iron ore pelletizing processes/technologies available.
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from
pellets and plant equipment, as well as the cost of the plants. Lately, however, the environmental aspects of ... that are charged into a blast furnace include lump ore, sintered ore and pellets.

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.
The plant used iron ore concentrate as input and produced superior iron ore pellets for blast furnace and direct reduced iron feed. Since then, Grate-Kiln Systems have been used for over 50 plants worldwide on both Magnetic and Hematite ores, with a total installed capacity of over 115 million TPA.
Iron Ore and Pellets 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.
In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln.
The image below shows a Great Lakes' freighter unloading iron ore pellets at the Algoma Steel plant, in Sault Ste. Marie, Ontario. Note the large piles of pellets onshore, and the two large blast furnaces in the background.

Iron ore pellets are superior to iron ore lumps in the subsequent iron making processes such as Blast furnace, DR furnace etc. Iron ore pellets with a nominal 64- 67% Fe, uniform porosity and better size help in faster reduction and higher metallization rates than the conventional iron ore lumps.
EU's iron ore production and is a major suppli-er of DR grade ore pellets to the MENA (Middle East North Africa) region, said their deliveries in 2012 totalled 26.3Mt of which pel-lets – both blast furnace and DR grade – were 22.0Mt. They supply about 40% of the EU's annual blast furnace pellet consumption. On the
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
