the chemical reactions that take place in the furnaces to the chemical composition of the different blends of steels. Since there are many types of steel that can be created, this specific description will focus on the process of making standard sheet steel. Sheet steel is long, thin steel that is usually shipped to customers in coils.

Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).

affect pellet quality. Occasionally, the chemical composition of the product pellets is also adjusted in this process to produce high quality pellets. A typical binder is bentonite or organic binder. Adding lime and/or dolomite to the ore adjusts the pellets so as to have the .
microstructures of the iron ore lump samples before and after the reducibility tests. Methods Tables 1 Shows the chemical compositions of the Itakpe Iron ore lumps. The iron ore concentrate has phosphorus in traces The morphologies of the ore was determined using the XRay Diffraction methods as shown in Figure 2 with other details in Table 2.
In the iron ore industry significant emphasis is placed throughout the mining process on meeting chemical composition specifiions for the export of fine ores, however, little has been published on the impliions of ore chemical composition for iron ore sinter and pellet product quality. The ore bulk composition, together with the nature of the minerals in the fine ore both play a critical ...

Iron ore is common in many mineral forms (hematite, magnetite, goethite, limonite or siderite) and has mineralspecific 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.
