[3] Evidence also exists for earlier iron metallurgy in parts Nigeria, Cameroon, and Central Africa, possibly from as early as around 2,000 BC. "Decisions set in slag: the human factor in African iron smelting". Les débuts de la métallurgie au Niger septentrional (Aïr, Azawagh, Ighazer, Termit). 2, No. This is a particular problem in Niger, where the charred stumps of ancient trees are a potential source of charcoal, and have sometimes been misidentified as smelting furnaces. We’ll get you noticed. W.W. Cline's compilation of eye-witness records of bloomery iron smelting over the past 250 years in Africa[34] is invaluable, and has been supplemented by more recent ethnoarchaeological and archaeological studies. [4] Iron ore is mined and produced in countries around the world including China, Australia, Brazil, India, Russia, Ukraine, South Africa, United States, Iran, Canada, Sweden and Kazakhstan. of the Lake Victoria region. In the southern regions of sub-Saharan Africa, the Bantu iron age migration continues, confining the San hunter-gatherer peoples ever further south. The second issue was the possible effect of "old carbon": wood or charcoal much older than the time at which iron was smelted. Smelting of magnetite and magnetite-ilmenite ores in the northern Lowveld, South Africa, ca. Unlike bloomery iron-workers in Europe, India or China, African metalworkers did not make use of water power to blow bellows in furnaces too large to be blown by hand-powered bellows. Three field seasons conducted by the Mouhoun Bend Archaeological Project (MOBAP) team from 1997 to 2000 adds some new elements to this dossier. [29] In a 2018 study, Archaeologist Augustin Holl also argues that an independent invention is most likely.[4]. [37] Natural draft furnaces were particularly characteristic of African savanna woodlands, and were used in two belts – across the Sahelian woodlands from Senegal in the west to Sudan in the east, and in the Brachystegia-Julbenardia (miombo) woodlands from southern Tanzania south to northern Zimbabwe. They are twisted iron rods ranging from <30 cm to >2m in length. This was the natural-draft furnace, which is designed to reach the temperatures necessary to form and drain slag by using a chimney effect – hot air leaving the topic of the furnace draws in more air through openings at the base. Independence: 17 August 1960 Area: 267,667 km2 Mining fact: In the 1970s, uranium was mined in Gabon to supply the French nuclear power industry. Muhammed, I.M., 1993. Rehren, T., Charlton, M., Shadrek, C., Humphris, J., Ige, A., Veldhuijen, H.A. Iron ore is the main ingredient in steel which is used in various applications around the world including structural engineering, manufacturing of cars and ships and general machinery. A nineteenth-century Ruhr in central Africa. For example, kisi pennies; a traditional form of iron currency used for trading in West Africa. The limitations to iron ore mining are not because of the size or grade of the ore, but rather the costs associated with mining the ore and transporting it. How much iron ore is left in the world? Unfortunately most radiocarbon dates for the initial spread of iron metallurgy in sub-Saharan Africa fall within this range. … Recently Asked Questions What themes do you see emerging in the Tao Te Ching? the early iron sites in east africa. [39][40] But not all large scale iron production in Africa was associated with natural draft furnaces – those of Meroe (Sudan, first to fifth centuries AD) were produced by slag-tapping bellows-driven furnaces,[41] and the large 18th-19th century iron industry of the Cameroon grasslands by non-tapping bellows-driven furnaces. [4] At Gbabiri, also in the Central African Republic, Eggert has found evidence of an iron reduction furnace and blacksmith workshop with earliest dates of 896-773 BC and 907-796 BC respectively.
