Preliminary Characterisation of Iron Ores for Steel Making ...
The iron ore lumps were reduced to smaller sizes using sledge hammer. The iron ore was further crushed using jaw crusher and then pulverized using vibratory cup miller (Herzog model) in order to obtain fine particle sizes of about 100 mesh (0.15 microns). The various equipment used for crushing and pulverization were set at 6 - 8 rpm.

Iron Ore - an overview | ScienceDirect Topics
Three potential sources (from the ores, sinter, or scrap) of naturally occurring radionuclides in the slag are discussed. Iron ores due to their geochemical properties scavenge radionuclides and heavy metals resulting in only trace levels of uranium in the main raw materials for iron-making; iron ore and coke ranging of 20–30 Bq/kg and 5 Bq/kg for limestone (Cooper, 2005).
