A comparative study of pellets, sinter and mixed ferrous burden

Raw materials. Commercially supplied iron ore pellets and sinter of size range 10–13 mm are utilised in the present study. Comparable to the utilisation in the industrial blast furnace, two types of olivine fluxed pellets (types 1 and 2) and one type of iron ore sinter are mixed in 40:20:40 ratio to form a ferrous raw material bed.

Iron ore pelletization

Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction (DR) processes.

Ore Pellet

The use of pellets and sinters is a typical example of rationally utilizing natural resources. The preparation and enrichment processes in the iron ore mines result in very fine-grained ores. An optimized process design will naturally include the sub-process to agglomerate the accumulated fine-grained ores by means of pelletizing or sintering.
