ABSTRACT OF THE DISCLOSURE : The invention is concerned with a waelz process of volatilizing zinc and lead from iron-containing and oxide- containing material in an inclined rotary kiln, which is charged at its upper end with the material together with solid carbonaceous reducing agent having a high content of volatile combustible constituents, wherein the reduction and volatili- zation are effected below the softening point of the charge, metallic iron-containing material is discharged from the lower end of the rotary kiln, combustion air is sucked into the lower end of the rotary kiln, and the exhaust gases are sucked from the upper end. The process of the invention is characterized in that oxygen-containing gases are blown at controlled rates through tubular air nozzles into the charge disposed over tubular air nozzles in that region of the heating- up zone wich begins where ignitable particles of the solid reducing agent begin to occur and which therminates at up to 50 % of the length of the kiln. This process results in a higher through put rate and permits the use of inexpensive reducing agents.
