Abstract

Language:

A silver-rich lead alloy was obtained through the recycling of two metallurgical wastes: lead paste from spent lead–acid batteries and jarosite residue from the hydrometallurgical production of zinc. Mixtures of these wastes were subjected to pyrometallurgical treatment utilizing sodium carbonate in a silicon carbide crucible at a temperature of 1200 °C. The chemical compositions of the resulting alloy and slag were analyzed using atomic absorption spectrometry. Results indicated successful alloy recovery, highlighting the viability of using metallurgical waste as a resource for valuable metal extraction. This method not only addresses the disposal challenges associated with lead and jarosite waste but also contributes to sustainable practices in metal recovery. Overall, the study demonstrates an effective pyrometallurgical route for reclaiming silver and mitigating environmental impacts from lead and jarosite waste materials.
