Oct 7, 2020Iron ore deposits in Missouri are divided into three main types: Precambrian-hosted hematite and magnetite, filled-sink hematite and limonite or brown iron ore deposits. Hematite (Fe 2 O 3) and magnetite (Fe 3 O 4) are the most economically significant ores. Limonite (FeO·OH·nH 2 O) was an important ore in the past.

Beneficiation = Improve Concentration of Iron. Ore is either Hematite (Fe2O3) or Magnetite (Fe3O4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content.

Sep 8, 2021Iron ore, or iron rock, is the host rock in which iron rich minerals can be extracted. The most commonly extracted minerals within iron ore are magnetite, hematite, goethite, and siderite. Iron is most commonly extracted from the iron rock by way of blast furnace at very high temperatures. Iron ores can contain oxide and other impurities.

The iron itself is usually found in the form of magnetite (Fe3O4) or hematite (Fe2O3), both of which are iron oxides. However, as much of the pure magnetite and hematite ore has already been mined, modern iron mines rely on aggregate ores such as taconite, which must be processed to remove non-iron-bearing components prior to smelting.
