Iron Ore Pellets – TGC Iran
TGC Iran – Premium-Quality Iron Ore Pellets for Modern Steelmaking
Iron ore pellets are one of the most important intermediary products in the steelmaking value chain — bridging the gap between raw iron ore and final steel products. At TGC Iran, we produce and supply iron ore pellets with consistent quality, high iron content, controlled size, and excellent mechanical properties, tailored to meet the demands of blast furnace and direct-reduction (DRI) steel plants.
After mining and beneficiation of raw iron ore (or concentrate), the fine iron-bearing powder is mixed with binding agents such as bentonite, limestone or dolomite, moisture, and other additives. Through a sequence of agglomeration — in pelletizing drums or discs — the mixture forms spherical pellets. These “green pellets” are then dried, hardened (indurated) in kilns at high temperature (usually 1200–1300 °C), cooled down, and screened for uniform size. The result: dense, hard, spherical pellets with controlled porosity and excellent metallurgical properties.
Pellets are sized typically between about 6 and 16 mm in diameter. Their iron content typically ranges from around 63 % up to 70 % (often ≈ 65 %) after proper processing — depending on the raw material and beneficiation process.
Key Quality Parameters of Pellets
When evaluating the quality of iron ore pellets, the following parameters are critical:
Iron (Fe) content: High Fe grade reduces the amount of gangue and slag, improving furnace yield and efficiency.
Impurities (SiO₂, Al₂O₃, P, S, etc.): Lower impurity content leads to higher quality steel and reduces furnace issues.
Mechanical strength (compressive strength, abrasion resistance): Ensures pellets survive handling, transport, and loading without excessive breakdown.
Porosity and structure: Proper porosity allows efficient gas-solid interactions inside furnaces, which improves reduction reactions and energy efficiency. Wikipedia+1
Size uniformity: Uniform pellet size ensures even burden distribution in the furnace, stable airflow, predictable reduction behavior
Why Pellets Are Preferred Over Raw Ore or Concentrate
Using high-quality iron ore pellets brings several advantages compared to raw ore or simple concentrate:
Improved Furnace Efficiency: Pellets have uniform composition and porosity, which improves gas flow, reduction speed, and thermal efficiency in blast furnaces or DRI furnaces. Wikipedia+1
Reduced Fuel and Energy Consumption: Because pellets are already agglomerated and have optimal reducibility, less coke/fuel is required per ton of iron produced, lowering energy costs. IIM Delhi+1
Lower Slag Volume & Waste: Better chemistry and lower impurities mean less slag formation, improving yield and decreasing waste materials. IIM Delhi+1
Enhanced Operational Stability: Uniform pellets reduce chances of segregation, blockages or uneven burden distribution in furnaces — leading to smoother, more reliable production runs. Beytoote+1
Logistics, Storage and Handling Benefits: Pellets are mechanically robust, have standard size and shape, making them easier to transport, store, and feed into furnaces compared with fines or raw ore. Wikipedia+1
Environmental and Economic Benefits: Lower energy, lower waste, higher yield — all contribute to cost-effectiveness and reduce environmental impact. Green Gubre Group+1

Typical Applications of Iron Ore Pellets from TGC Iran
Iron ore pellets are used as primary feedstock in steel production processes, including but not limited to:
Blast Furnace Operations — as high-grade feed reducing the need for sinter or lump ore.
Direct Reduction Iron (DRI) Plants — where pellets are reduced under controlled gas atmospheres to produce sponge iron. Green Gubre Group+1
Electric Arc Furnaces (EAF) — as part of the raw material mix, to produce high-quality steel with more consistent composition.
Infrastructure, Construction, Automotive, Heavy Machinery, Shipbuilding — end products from pellet-fed steel are used across these industries.
