Indian iron ores are suffering from high amounts of alumina and loss on ignition (LOI), which are deleterious constituents in both the pelletizing as well as iron making processes. Iron ore fines utilized in pellet making consist of alumina in the range of 3.20–3.35% and LOI in the range of 3.50–3.70%. Detailed palletization studies have been carried out on high alumina …

Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources.
