Measurement of metallic iron in steel making slags
An integrated steel plant generates 200-250 kg of steel making slag for every tonne of steel produced. These slags contain non-uniformly distributed iron in metallic form, inevitably carried into the slag pot during de-slagging. The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products with varying metallic values.

Steelmaking Slag Beneficiation by Magnetic Separator and
Iron and steelmaking slags are defined as the solid material resulting from the interaction of flux and impurities in the smelting and refining of steels. It is a by-product of steel making and is produced during the separation of the molten steel from impurities in steel making furnaces. That is, the slag occurs during steel making in liquid

How Iron Was Made
Mottled iron was also cast into the sand in the shape of long bars. In this case the iron would be cast with slag and all and the slag would float to the top of the bars where it would break off. The iron then froze into heavy ingots or "pigs". Pig iron was an intermediate step in the making of wrought iron.

Bog iron
Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface.

What are Properties of Wrought Iron
The microstructure of wrought iron shows dark slag inclusions in ferrite. It is soft, ductile, fibrous variety that is produced from a semifused mass of relatively pure iron globules partially surrounded by slag.

Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.
