Results of development of processing technology of zinc agglomerated cakes by Waelz-process on large-sized (60.0×4.0) Waelz-furnace at Chelyabinsk Zinc Plant are described. Technical decisions on improvement of technology and Waelz-process equipment are resulted. In the course of development following technical and economic indices are reached: productivity of the kiln 320 t/day, campaign of the furnace 412 days, natural gas is used basically only at kiln start up.
