Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising Plant, we turn the fine ore into small balls in large drums.

— Iron ore is a crucial raw material for the global steel industry, and its supply chain is a complex network that involves multiple stakeholders and activities. The iron ore supply chain begins with the mining of iron ore, which is then transported to processing plants for beneficiation and further refinement. The refined iron ore is then transported to …
This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications.
— 98% of iron ore is used as raw material for steel and iron. Iron ore pellets are preferred instead of raw ore when smelting steel because pelletization can maximize the use of iron ore and improve the blast furnace performance. What are iron ore pellets? Iron ore pellets are spheres of typically 8-16 mm to be used as feedstock for blast furnaces.
Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature.
