Mineral Resource of the Month: Iron and Steel Slag

Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten ...

Slag-What is it Good for? - USGS

We looked specifically at ferrous slag, the leftover material from the smelting of iron and steel, in the Chicago-Gary area of Illinois and Indiana. Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of ...

Iron Ore Mining Techniques Metal Extraction

Iron ore is the unrefined substance utilized to formulate pig iron, which is one of the most important untreated materials to compose steel. 98% of the hauled out iron ore is used to produce steel. Uncontaminated iron ore is almost nameless on the exterior of the Earth apart from the combination of Fe-Ni alloys from meteorites and very atypical forms of unfathomable mantle xenoliths.
