FIELD: non-ferrous metal metallurgy, namely processing of zinc cakes in rotary kiln.
SUBSTANCE: method comprises steps of filtering pulp of zinc cake in press filters; mixing filtered cake having humidity 19 - 23% with coke fines, fluxing additives, circulating dust or with other dust-like zinc-containing products suitable for rotary-kiln processing in apparatus providing turbulent motion of materials; then subjecting prepared charge to rotary-kiln processing.
EFFECT: improved efficiency of rotary kiln due to lowered yield of reverse dust, enhanced quality of rotary-kiln processed oxide due to increased concentration of zinc and lead and lowered content of non-sublimated components in it.
