In the quest for an economical and environmentally friendly reclamation of metallurgical dusts generated during pyrometallurgical operations, the goal has been the separation and recovery of most of the components, as well as the complete recycle of all the reagents. Effluents have been avoided, within acceptable economic parameters. This presentation, which can be applied to a large spectrum of dusts and other residual materials, has focused on the dusts generated by the operation of Secondary Copper Smelters. Those dusts show a wide range of components, including zinc, lead, copper, cadmium, tin, chlorine and alkalis. The present work deals with the use of ammonium salts in the separation and recovery of the above mentioned elements in a marketable form. Most of the chemistry and techniques involved have been already confirmed in commercial scale operations. Others have gone through pilot scale tests or bench scale tests. The recycle of reagents has also been confirmed at the same operating levels. A preliminary evaluation indicates that the chosen route, in addition to a viable economy, offers a complete and safe reclamation within the most strict environmental regulations.
