The iron ore used presents a low MgO content (0.01%) and a high Al2O3 content (2.99%). It was seen that raising the MgO content in the sinter, from 1.4 to 2.6%, increased the FeO content and decreased productivity and the RI, RDI and TI indices [13]. 2.1.4.
2.1 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).

FeO quantification is done simultaneously with the quantitative phase analysis and is reported along with the phase composition. A comparison of FeO values, as extracted from the XRD data, with the reference values, obtained by wet chemistry, is shown in Figure 3. We see a very good agreement between the XRD results and the given reference values.
The reason for the presentation of iron as FeO rather than Fe lies in the fact that the process of refining iron was still underdeveloped and the reached temperature was not sufficient for high-quality ore reduction process starting from the Fe 2 O 3 to the metallic iron.

redox state of iron can be particularly important. The iron in common rocks is in the Fe2+and Fe3+states, usually present in minerals as the nominal chemical components FeO and Fe 2 O 3, respectively. The analytical procedure described here permits the analysis of FeO in a sample by titration. How it works 1.
The pelletizing process of iron ore is a consolidation method to obtain high-strength pellet; this includes granulation of the mixed materials (such as iron ore, bentonite and flux), drying of green pellet, firing of green pellet with combustion of fuel in burden bed, and cooling.
RAPID ANALYSIS OF CHROMITE AND CHROME ORE 33 The procedures described here provide for the determination of Cr2O3, A12O3 . SiO2, Fe (total), FeO, MgO, Ti02, MnO, V2O3, NiO, CaO, and H2O. A flow diagram outlining the major steps in the analysis is shown in figure 5.
Reduction procedure. Industrially iron is produced from iron ores, principally hematite (Fe 2 O 3), magnetite (Fe 3 O 4) by a carbothermic reaction that is reduction with carbon, in a blast furnace at temperatures about 800–1,600°C.In the blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone are fed into the top of the furnace, while blast of heated air is forced ...
XRD analysis detected wustite (FeO), fayalite (Fe 2 SiO 4), and hercynite (FeAl 2 O 4) as major phases in the briquette sample. The presence of such phases suggests the high affinity of FeO towards silica and alumina for which low melting fayalite forms, melts early and hinders CO gas passage to the core. ... Manganiferous iron ore is the type ...
If possible, use wet chemical analysis - titration - to analyze bath FeO and Fe2O3. Unfortunately, modern analytical methods, e.g. XRF, ICP-OES, only provide total iron …

Iron itself is found in one of the following forms: magnetite (Fe304), hematite (Fe203), goethite (FeO (OH)), limonite (FeO (OH).n (H20)), or siderite (FeC03). Pig iron, one of the necessary raw materials in making steel, is comprised partially of iron ore. Approximately 98 percent of the iron ore mined is used to make steel.
in ore/mineral analysis. The separation of soluble and insoluble species should be near . The exact choice of method for opening of an ore depends on the nature of the ore, the element of interest and its chemical properties. The selection of the appropriate method of sample decomposition is very important for correct analysis.
