METHOD AND APPARATUS FOR REDUCTION OF MATERIAL CONTAINING METAL OXIDE |
摘要 |
Method and apparatus for producing matte and/or metal from sulphidic fine-grained ore or ore concentrate. The ore or ore concentrate is smelted in a flame chamber in such a way that at least part of the solid material in the flame chamber melts and flows downward into a smelt bath furnace, on top of which the flame chamber is disposed. Volatile metallic and sulphuric components are conducted upward from the flame chamber to a fluidized bed reactor to be utilized as fluidizing gas, the gases being rapidly cooled down in the fluidized bed. |
