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.
