A new approach for recovering iron from iron ore

A new approach for SMR was developed for efficient iron recovery from iron ore tailings. • An iron concentrate with 58.67% Fe at an iron recovery of 57.82% was obtained. • Hematite and siderite were transformed into magnetite during the SMR process. • The SMR reactor showed good performances in terms of operation, control and product.

Mineral Resource of the Month: Iron Ore EARTH

In nature, elemental iron is found largely in either magnetite or hematite, both iron ore minerals. Nearly all iron ore — whether used directly as lump ore or converted to briquettes, concentrates, pellets or sinter — is used to make steel. In the United States, steelmaking accounts for almost 99 percent of iron ore consumption. Minor amounts are consumed in the production of cast iron

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
