A process for the reduction of oxidic iron minerals in order to obtain a preliminary product, whose iron content is present, at least in part, in metallic form, by reducing treatment of shaped bodies made of oxidic iron minerals with a solid carbonaceous reducing agent, in a rotary tube furnace, the shaped bodies being in a bed of solid carbonaceous reducing agent and the CO acting in a reducing manner developing in said bed, characterized in that the shaped bodies are incorporated a part of the reducing agent required for the total reduction work, in the form of a fuel containing volatile components, these shaped bodies being preliminarily reduced with the aid of the incorporated fuel, and being finished with the help of an outer bed of another reducing agent.
