    Abstract:

    Most of the SO2 produced in the pyrometallurgical processing of non-ferrous metals is currently used to make sulfuric acid. This process, initially conceived as a way to mitigate atmospheric pollution with SO2, has become in some particular cases a source for additional income due to local or geographical demand of sulfuric acid mainly for the use in hydrometallurgical processing of ores. However, the convenience of sulfuric acid production from smelter gases is currently scrutinized due to the increasing instability of the local acid market and the increasing interest of developing alternative methods to treat the SO2 from the gaseous effluents in nonferrous smelting processes. In this framework, this paper presents a critical review of alternative methods to treat SO2 laden smelter gases to produced elemental sulfur in order to comply with ever stringent environmental regulations as opposed to the conventional method of producing sulfuric acid from the SO2.
