Iron Extraction - W3spoint

The carbon monoxide REDUCES the iron oxide in the ore, into molten iron which flows to the bottom of the furnace. Limestone is added to remove acidic impurities forming a molten slag which floats on top of the iron. The carbon monoxide combines with oxygen from the iron ore to produce carbon dioxide. This is called OXIDATION.

How Is Iron Extracted From the Earth? - Reference

2020-03-26  Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances. Through this process, ferrous oxide

Iron Production - Chemistry LibreTexts

2020-08-15  The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron. This is accomplished by the method of pyrometallurgy, a high temperature process. The high temperatures are needed for the reduction of iron and the oxidation of the limestone which will be seen below.

Iron(II,III) oxide - Wikipedia

Iron (II,III) oxide is the chemical compound with formula Fe 3 O 4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron (II) oxide (FeO), which is rare, and iron (III) oxide (Fe 2 O 3) also known as hematite. It contains both Fe 2+ and Fe 3+ ions and is sometimes formulated as FeO ∙ Fe 2 O 3.
