  • African iron production and ironworking technologies:

    The process begins with the sourcing and extraction of raw materials, including clay, smelting is the process of iron production most commonly encountered in the archaeological record (socalled because the iron remains solid throughout the process, growing as a 菰bloom虎 of iron rather than melting as in a blast furnace), and it was practiced across much of precolonialWhat is Iron extraction? Iron extraction is a process Iron (metal) is extracted from iron ore, also called as hematite, in the container It uses blast furnace to extract iron Iron is extracted through the process of reduction with carbon or carbon dioxide This raw material, iron ore, contains iron oxide, and this isIron Extraction: The Process Of Iron Extraction | ipl
