| Abstract | Results of development of calcination technology of Waelz-oxide in the tube-type furnace (41.0×2.5 m) of the Chelyabinsk Zinc Plant are submitted. Technology key parameters are presented. The technological scheme is shown. Calcination of Waelz-oxide is one of the widespread technologies of its preparation for hydrometallurgical processing till now. Its advantages are oxidation of sulphides, organic reducers in Waelz-fumes, chlorine and fluorine removal. To reduce mechanical dust carry-over from rotating furnace and amount of secondary fumes, intensification of calcination process Waelz-oxide is subjected to pelletization. |
