Iron processing - Ores | Britannica

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...

Iron Ore - an overview | ScienceDirect Topics

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

Iron Ore | ScienceDirect

Waste gases from iron ore fine preparations for blast furnace ironmaking, or sintering, contain minute quantities of acidic species, dust, and dioxin pollutants, but because of the very large quantities of iron ore processed and the large volume throughput of air involved, sintering is a major source of these emissions and also CO 2 into the atmosphere.
