Zusammenfassung:A method for determining the content of at least metallic iron (Femet) in sponge iron or a sample thereof produced by direct reduction from iron ore. For this purpose, a mathematical model is provided, whose model output variable (Amod) is described as a function of the content of at least metallic iron (Femet) of the sponge iron or sample thereof, this mathematical model having an effective medium approximation (EMA) for the permeability (μeff) and electrical conductivity (σeff) of the sponge iron or sample thereof.
