Iron metallurgy in Africa Wikipedia

The topic of early ironmetallurgy in subSaharan Africa encompasses both studies of the technology and archaeology of indigenous ironproduction.. 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.
