How did the Bantu smelt iron? –

 · The earliest bloomery smelting of iron is found at Tell Hammeh, Jordan around 930 BC (14C dating). Who is the first blacksmith? Blacksmithing origins first trace back to 1500 BC when the Hittites discovered the process of forging and tempering iron ore. When the Hittites were stered in 1200 BC so was their knowledge and understanding of basic iron work. When was smelting .

Energy Use in US Steel Manufacturing

This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid iron that flows from the bottom of the blast ...

Iron: From mythical to mundane

 · We don't know when, how or by whom iron smelting was first discovered, but we know how the process was done. A furnace is constructed: the smallest is a cylinder about three feet high, but they can be much larger. Iron ore and charcoal are dumped into the furnace, in alternating layers; it helps to add lime as well. A fire is started, perhaps air is pumped in the bottom with a bellows. The ...

Hurstwic: Iron Production in the Viking Age

The iron ore shown to the right was excavated from Skógar, a Vikingage ironmaking site in Iceland. The larger piece is about 2cm (less than 1in) in the long dimension. Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.

The Hittites

Iron probably was not the mythical secret weapon which explained Hittite military success. However, they did develop a smelting process capable of producing iron tools, weapons, and ornamental objects. Their process was the result of years of metalworking experience, not simply an accidental byproduct of an iron rock falling into a fire.
