2.1 Material 2.1.1 Sample Collection. Indian iron ore was collected from Kiruburu mine's Jharkhand, in the form of fines (<5 mm). Afterward, the ore concentration was found to be 62.42% Fe, 2.98% SiO 2, and 1.91% Al 2 O 3 and presented 3.61% LOI. Since it has a significant LOI percentage, drying and induration of the ore is imperative …

Blaine fineness is one of the most important parameters in pelletising. While the lower Blaine fineness does not provide sufficient strength to the both green pellet and indurated pellet, excessively high Blaine fineness causes problem in pellet making. Optimum Blaine fineness of iron ore in the range of 1700–2250 cm2/g is usually used for good quality …

Optimum Blaine fineness of iron ore in the range of 1700–2250 cm 2 /g is usually used for good quality pellet making. However, when a material of high Blaine fineness is produced after beneficiation and there is no option to control the fineness, the pellet making from high Blaine fineness ore becomes obligatory.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
