Iron processing Ores, Surface Mining, Sintering, and
网页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 red;

Iron Ore Reduction by Biomass Volatiles SpringerLink
网页2021年2月8日 Since the iron ores contain goethite, which is a hydrated phase that typically decomposes between 280 and 425 °C,the mass loss is mainly attributed to its decomposition. The total mass loss of these iron ores obtained at 425 °C shows the amount of the goethite content in iron ore A (8.5%) is higher than in iron ore B (3.7%).

The Distribution of Iron in Nature SpringerLink
网页Abstract. Iron, in the form of various combined ores, is one of the most common elements, constituting about 5% of the earth’s crust. The most important iron-containing minerals are the oxides and sulfides. Hematite (red iron ore, Fe 2 O 3 ), magnetite (loadstone, Fe 3 O 4 ), and goethite (hydrous iron oxide, FeO 2 H) belong to the former
