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).
Raw Materials Management that goes beyond a basic approach requires an in-depth understanding of impacting/influencing factors. These factors fall into two categories: external uncertainties (issues largely beyond the influence of any individual firm, although they require firm-level attention and adaptation) and internal conditions (issues under direct influence of firms related to the ...

Iron ore - Wikipedia, the free encyclopedia . Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite ...
