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 requires ...

Mitigating iron foulants in refinery processes

The iron moves in a myriad of paths from pipe to feed to reactor. Ultimately, if these types of problems are not dealt with, the fouling particles can reduce cycle lengths, greatly impacting reactor profitability. Shown below is the chemistry of how iron compounds are generated during the refining process and become entrained with the feed.

iron: Production and Refining | Infoplease

Ductile iron is strong, shock resistant, and easily machined. Wrought iron is commercially purified iron. In the Aston process, pig iron is refined in a Bessemer converter and then poured into molten iron silicate slag. The resulting semisolid mass is passed between rollers that squeeze out most of the slag.

Apr 04, 2012 · On the other hand, BOF slag mainly contains CaO added as a refining agent, and SiO 2 and iron oxides produced by oxidation refining process. The EAF slag is classified into two types, oxidation slag and reduction slag, which are produced during steel refining and reduction of iron oxide to metallic iron, respectively.

Refining (metallurgy) - Wikipedia

The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon. To produce a forgeable product a further process was needed, usually described as fining, rather than refining. From the 16th century, this was undertaken in a finery forge. At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually superseded by the production of mild steel by the Bessemer process.

Electrolytic iron - Wikipedia

Electrolytic iron is considered the “wet process” since electrolysis requires electric charges to move through a liquid solution. This action causes a chemical reaction called electrolytic refining. The result of electrolytic refining produces electrolytic iron. An anode (raw material) and a cathode (base plate) are immersed into an ...

Steelmaking and Refining | Introduction to Chemistry

The term “refining” is used in a narrower context.

For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
