ABSTRACT:
A method and apparatus for recovering primary metals from pyrometallurgical process dust, in which a vertical shaft retort, situated in a furnace or afterburner associated with a pyrometallurgical apparatus, such as an inclined rotary reduction smelter, and preferably having a tapered cross-section with the larger end at the bottom, receives greenball pellets from a pelletizer, vaporizes volatile metal metals therein, and removes them to an associated volatile metal recovery apparatus, while reducing and recovering the major metal oxide components in the pellets in metallized form.
