Iron metallurgy in Africa - Wikipedia
Some recent studies date the inception of iron metallurgy in Africa between 3,000 and 2,500 BCE. Evidence exists for earlier iron metallurgy in parts of Nigeria, Cameroon, and Central Africa, possibly from as early as around 2,000 BCE. Some evidence from historical linguistics suggests that the Nok culture of Nigeria may have practiced iron smelting from as early as

Most early processes in Europe and Africa involved smelting iron ore in a bloomery, where the temperature is kept low enough so that the iron does not melt. This produces a spongy mass of iron called a bloom, which then must be consolidated with a hammer to produce wrought iron. Peter Kolbe (1675-1726) was a Dutch astronomer and naturalist.
