The iron in a cargo of iron ore is chemically bound with other elements and therefore it contains no metallic (or free)iron. If the cargo contains any metallic iron (Feo), then it must be a DRI derivative: DRI (A) and (B) cargoes typically contain about 85% metallic iron,whereas in blends containing DRI (C) it can be as low as1% or 2%.

Iron ore

Rich iron ore contains more than 57 % iron, less than 8–10 % silica, less than 0.15 % sulphur and phosphorus. It is a product of natural enrichment of banded iron formations originated by leaching quartz and decomposition of silicates during long-term weathering or metamorphosis. Lean iron ores may contain 26 % iron min.

Can Penalty Elements in Iron Ore be Determined with XRF?

 · Iron ores are rocks and minerals from which metallic iron can be economically extracted during the mining process. Waste elements other than iron (Fe) in iron ore dilute the overall grade of the ore and incur a smelter penalty. Penalty elements change the physical properties of iron and can impede the proper operation of the smelting facility.
