The history of iron casting part 1 - The C.A. Lawton Co.
During this time, they hammered or pounded the metal to create tools and weapons. They found and extracted it from meteorites and used the ore to make spearheads, tools and other trinkets. Between 2000 BCE and 1200 BCE, the Hittites developed a process for smelting the iron – heating its ore to purify it – expanding its usability.
How Iron is Produced - Metal Casting Institute
The only pure iron known to exist naturally comes from fallen meteorites. The iron we extract from earth-based ores is found in minerals formed by the combination of iron with other elements. Iron oxides are the most common. The iron-bearing minerals in the earth's crust (refereed to as iron ore) have the highest concentration of iron content ...

From Ore to Iron with Smelting and Direct Iron Reduction
The Hismelt process employs a single smelt reduction vessel (SRV) where iron oxide fines are injected deep into hot metal melt, which instantly reduces the ore to produce iron and carbon monoxide. Flux and coal are also injected into the bath near the bottom, which enables carbon replenishment and captures impurities (silica, etc.).
Manufacturing Process of Steel – Properties Fabrication Uses
The raw materials for producing molten iron are iron ore, coking coal and fluxes (materials that help the chemical process) – mainly limestone. The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron. The reaction between air and the fuel generates carbon monoxide.

Steelmaking - Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrap.In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. ...
Ancient Metallurgy - University of California, San Diego
The production of steel requires the removal of more of the impurities in iron ore than iron production does, often through the application of greater heat than ancient furnaces could produce. It is easy to think of steel as iron ore to which carbon is added, but in actual production it was often cast iron from which carbon was removed, a ...
