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 (OH)), limonite ...

Benefits of Pelletized Iron Ore. In addition to the factors listed above, iron ore pellets also offer a number of benefits to steel producers, some of which include: Improved productivity per cubic meter of blast furnace 1. Lower emissions and dust compared to sinter 1. Reduced requirement of coking coal. Improved handling and transportation.

The chemical analysis and particle size distribution for the iron ore nes and the pellet nes used for the sinter pot trials are shown in Tables 2 and 3 respectively. Table 4 shows the iron ore blend mix proportion and mean particle size (MPS) for the iron ore blend for all the experiments. The high Fe and low LOI concentrate within the pellet

The iron ore fines with less than 10 mm size are usually fed to the sintering process, and only limited fraction (less than 20%) of − 150 micron size of iron ore fines are allowed in the sintering process. The finer sized iron ore may choke the sinter bed and hinder the uniform air suction through the bed.
