Abstract A method for the melt reduction of iron ores, in which the iron oxide is reduced substantially in the liquid state and the energy required for the heat balance of the process is generated by adding carbonaceous fuels to the melt and by afterburning the resulting reaction gases, mainly CO and H2, the reaction gases being afterburned successively two or more times in oxygen-containing gas jets that blow into reaction spaces which are effectively independent of each other.
