Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ), goethite (FeO

· Abstract. In iron making process, sintering of iron ore fines is an integral step to utilize not only the ore fines but also to introduce a part of flux (limestone and dolomite) along with the sinter in blast furnace burden. In this way, the productivity of the furnace considerably improves. In this paper, some fundamental aspects such as the

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
