Roaster with stabilized fluidized bed for roasting zinc

2002-1-18  Zinc concentrate (ZnS) is roasted to oxidize its sulfur component into sulfur dioxide, thereby producing zinc calcine (ZnO). There are various types of roasters, which are furnaces used for the roasting process, and the roasters include, for example concerning zinc, a multiple hearth roaster, a flash roaster, a fluidized bed roaster, etc.
