ABSTRACT:
Effluent gas containing SO.sub.2 and/or nitrogen oxides of various forms (referred to as NO.sub.x) are irradiated with an ionizing radiation to form aerosol. The aerosol is collected by a collecting means to form a collected material containing sulfur dioxide and nitrogen oxides. Effective components are recovered from the collected material by subjecting it either to steam-roasting with or without addition of ore of low grade, solid waste generated from smelting processes, copper-containing pyrite cinders or an alkali earth metal compound to the collected material, or to thermal decomposition.
