All indigenous African iron smelting processes are variants of the bloomery process. A much wider range of bloomery smelting processes has been recorded on the African continent than elsewhere in the Old World, probably because bloomeries remained in use into the 20th century in many parts of sub-Saharan Africa, whereas in Europe and most parts of Asia they were replaced by the blast furnacebefore most varieties of bloomeries could be recorded. W.W. Cline's compilation o

24/01/2020 The African Iron Age, also known as the Early Iron Age Industrial Complex, is traditionally considered that period in Africa between the second century CE up to about 1000 CE when iron smelting was practiced. In Africa, unlike Europe and Asia, the Iron Age is not prefaced by a Bronze or Copper Age, but rather all the metals were brought together.

Igneous Complex in South Africa are used to investigate the effects of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity. The electric energy consumption is highly related to the SiO 2 content of chrome ores. The lowest electric consumption of 3.31 MWh/t is required when the SiO 2 %
•Arcelor Mittal South Africa uses lump (-25 +8 mm) iron ore in their blast furnaces and fine iron ore (-8 +0.2 mm) undergoes agglomeration in sinter plants before feeding to the blast furnaces. •The blast furnaces produce pig iron which is then converted to steel in basic oxygen furnaces (BOF). The steel produced is then transformed into numerous semi-fabricated products. It is
Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite
