How Is Iron Extracted From the Earth? - Reference

2020-3-26  Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

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

Extraction of Metals Good Science

The crushed ore is mixed with carbon and limestone, then heated to a molten state (smelted) in a blast furnace. In the subsequent chemical reaction, the metal-containing compound is reduced (loses oxygen) to form pure metal, and the carbon is oxidised (gains oxygen) to form carbon dioxide.

How is Iron Refined from Ore? (with pictures)

Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore
