Indian blast furnaces are fed with lump iron ore (10 - 40 mm) and sinter as burden. Sinter is a prepared burden, where iron ore fines of size -10 + 0.15 mm are agglomerated using mainly flux and coke. Iron ore fines of less than 0.15 mm are not utilized in sintering technology and hence are mostly discarded at mines during processing as slime.
