FIELD: metallurgy.
SUBSTANCE: oxidised zinc-containing materials with coke dross as a hard carbon reducer are supplied into a rotary tubular furnace and exposed to Waelz process with supply of blow in the form of a steam and air mixture into zone of temperatures 1050-1150°C with content of steam in the mixture 14-25%.
EFFECT: reduced consumption of a reducer and content of zinc and lead in a clinker, eliminates softening of material in a furnace.
