2024910· The pelletizing process mostly uses high-grade iron ore such as magnetite (Fe 3 O 4) as the main raw material, which has been depleted due to the increasing demand for pellet production. The current study attempted to replace magnetite ore with low-grade limonite ore (Fe 2 O 3 ∙nH 2 O) at different additional levels (10, 30, 50 and 100 wt%).

103· The constant demand for iron ore leads to the need to mine even low-grade deposits. The diminished quality of natural resources is countered by economic, ecological, and technological restrictions that require the processing of the extracted iron ore. An enrichment of iron ore can be achieved by separating unwanted components. This enrichment of iron ore …

Iron ore pellets are produced through a process called pelletizing where iron ore fines are mixed with additives, formed into balls, and then fired to increase strength. This process creates uniform feed for blast furnaces. The main stages are: raw material preparation, ball formation in discs, induration (heat hardening) through drying, firing, and cooling, and final screening and storage

PDF | Global iron ore production has grown dramatically in recent years to meet increasing world steel demand, especially in Asia. High grade lump ore resources are being depleted and a greater amount of fine concentrate/pellet feed will enter into production as lower grade deposits are mined. Integrated steel plants need to make convenient use of the available iron ore resources …
