Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
In the study of natural ores,, it was found that the chemical composition and microstructure of natural iron from Muko deposits in Uganda corresponds to the demands on high grade iron ore. Precisely, the Fe, silica, and alumina contents indicate that they can profitably be used for iron production.
Iron ore is common in many mineral forms (hematite, magnetite, goethite, limonite or siderite) and has mineral-specific analysis requirements. Borate fusion with XRF analysis is an extremely robust technique for major and minor elemental analysis in complex mineralization and offers highly precise and accurate results for iron ore samples.
This type of cast iron is called grey cast iron, and its main characteristic is the grey-colored carbon flakes in its composition. To produce cast iron, iron ore is deoxidized in a blast furnace. When the ore is melted, it is poured into molds.

The composition of the iron-ore part of the sintering charge was varied in relation to the position of the sinter in the system S–Q–W (Table 1). The sinterings were carried out in a laboratory cup 430 mm in diameter and 260 mm high.
For an example of the application of cluster analysis to iron ore evaluation and grade control, the reader is referred to the contribution by Paine et al. (2012), who evaluated a large number of iron ore samples from an iron ore deposit.

The iron ore industry is an important segment of the world economy. The main mineral oxides are magnetite and hematite. The composition of iron ore playsan important role in both the iron (blast furnace) and steelmaking operations.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its iron-content.
Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. Hematite is mined in some of the largest mines in the world.
