Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Some evidence from historical linguistics suggests that the Nok culture of Nigeria may have practiced iron smelting from as early as 1000 BC; archaeological evidence dates this not later than 550 BC. Iron ore is placed in a blast furnace with coke (carbon), in which the oxygen is converted to carbon dioxide, andf the molten iron can be drawn off from the bottom. It consists of strongly heating a sample of the material at a specified temperature, allowing volatile substances to escape, until its mass ceases to change.This may be done in air, or in some other reactive or inert atmosphere.
