4.B  IRON ORE PELLETS 64.0% - 67.0% FE  (TOTAL IRON)

Iron ore pellets are essential for high-quality and efficient steel production. Formed by agglomerating fine iron ore concentrate, these pellets offer a uniform and pure iron source for both blast furnaces and direct reduction processes. They enhance metallurgical performance, reduce energy consumption, and lower emissions, contributing to environmentally friendly and cost-effective steel production.

Fe (Total Iron):                      Typically  around 64-67%

SiO2 (Silica):                          Usually less than 3.0%

Al2O3 (Alumina):                  Commonly less than 2.5%

P (Phosphorus):                    Generally below 0.05%

S (Sulfur):                               Typically less than 0.05%

Moisture:                                Usually around 1.0% to 10% (depending on storage conditions)

Size:                                        Majority (90%+) pellets are between 9.5 mm to 16 mm in diameter

Basicity (CaO/SiO2):           Varies with the pellet grade, typically around 0.5 to 0.8

Tumbler Index:                      Greater than 95% (measures durability during handling)

Abrasion Index:                     Less than 5% (measures fines generation during handling)

Compressive Strength:        250 kg/pellet minimum

Bulk Density:                          Approximately 2.0 to 2.5 tonnes/m³
