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).
