Study of the reactions between iron ore slag and refractories

There are different compositions of iron ores that are used. The two mains are hematite (Fe 2O3) and magnetite (Fe 3O4). The one that is processing at LKAB Kiruna, is magnetite rich iron ore. The magnetite is mixed with other impurities and has to be extracted from the ground. 1 There are different types of iron ore used to make steel: fines (fine ore), lump, and pellets.

For example, iron ores are often found in hard igneous or metamorphic rock formations, so waste rock from iron or taconite ore processing is usually hard and dense. For the most part, lead and zinc ores are found in limestone and dolomite rock, so the waste rock from processing these ores will have characteristics much like other carbonate aggregates.

Iron Ore Statistics and Information - USGS

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3).

Vanadium processing Britannica

11-04-2021  After removing the slag, the molten pig iron is blown with oxygen to form a new slag containing 12–24 percent vanadium pentoxide (V 2 O 5), which is used in the further processing of the metal. Vanadium is extracted from carnotite as a coproduct with uranium by leaching the ore concentrate for 24 hours with hot sulfuric acid and an oxidant such as sodium chlorate.
