Refining (metallurgy) - Wikipedia

 · Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. 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.

Steelmaking and Refining | Introduction to Chemistry

The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal known as finers metal or refined iron.

Pyrophoric Iron Removal | Oil Refining | Carus Corporation

During the refining of crude petroleum, the sulfur component of the crude oil reacts with the specialty alloy steel processing equipment producing iron sulfide scale. Pyrophoric iron sulfide scale, when exposed to air, reacts exothermically and can result in a fire. Toxic sulfide odors can also be formed during these turnarounds.

Permanganate oxidizes pyrophoric iron sulfide to iron sulfate eliminating the potential for exothermic reactions and fires or explosions during shut downs for maintenance of refinery process equipment. Permanganate treatment also controls toxic odors by oxidizing the sulfides to odorless sulfates.

The Refining Process - How Oil Refining Works - Science

Newer techniques use Chemical processing on some of the fractions to make others, in a process called conversion. Chemical processing, for example, can break longer chains into shorter ones. This allows a refinery to turn diesel fuel into gasoline depending on the demand for gasoline. Refineries must treat the fractions to remove impurities.

The term "refining" is used in a narrower context. Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
