Both the collapsed answers that it ranges from 10 mm to 30 mm are correct. However a little elaboration would be useful. For proper blast to be maintained there should be sufficient space between pieces of iron ore. Therefore the ore should not be...
Chemical analysis of different size fractions of hard massive ores indicates that there is a gradual decrease in iron content and increase in alumina content from coarser to finer size fractions. During processing, they are resistant to the crushing, resulting in generation of coarser fractions. The sized ore or lumps, having size

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
