We have performed thermodynamic modeling of the reduction of iron scale (production waste of metallurgy and machine-building) by products of incomplete conversion of methane in oxygen for developing a process of obtaining iron powder with the use of a plasma jet. We have calculated the equilibrium composition of the gas phase and condensed interaction products at various temperatures and initial compositions of the reducing medium. The optimal process parameters providing reduction of scale to pure iron, i.e., the temperature range, the methane/oxygen ratio in the gaseous medium, and the scale/gas mixture mass ratio, have been determined.
