The invention relates to a method of utilizing secondary raw materials containing iron, zinc and lead, preferably steelmaking dusts, in a rotary tubular furnace customarily equipped for the rolling process, with basically adjusted rolling slag. By reducing the portion of the carbon carriers in the burden, the energy balance of the rolling process is improved on one hand, and the throughput of the rotary tubular furnace used is increased on the other hand. By improving the quality of the rolling slag, the capability of utilizing the same is favored.
