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.

Refinery | Space Engineers Wiki | Fandom
The Refinery is a block in Space Engineers, necessary for converting raw ores into useful refined materials . The Refinery can process all ore types while the similar Basic Refinery only processes iron, nickel, cobalt, silicon, magnesium and stone; however, it can process those ores faster than the Basic Refinery and uses less electricity.

Iron Ore | HowStuffWorks
Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...

Processes and Procedures in the Extraction of Iron ...
The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

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.

What Is Iron Ore Beneficiation? (with pictures)
Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it. The iron content of the ore needs to be increased ...

How Iron Was Made - Saugus Iron Works National Historic ...
Introduction. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers replaced ...

This pig iron was a brittle cast iron containing a high percentage of carbon (2–4%), which made it unsuitable for malleable or wrought iron. The pig iron therefore had to be re-smelted in special furnaces in the forge. This was know as the refining process, in which surplus carbon was burnt off, leaving the iron pure, soft and malleable or ...

iron processing | Britannica
Direct reduction, in which iron ores are reduced at temperatures below the metal's melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957. Few of these techniques survived, and those that did were extensively modified.
