Selenium extraction process contained in the sulfuric acid obtained in the factories that use the nitration process, characterized by comprising two phases, the first of which comprises the previous treatment of the hot sulfuric acid with any of the reagents of the order of the ammonia, any ammonium compound, selenium itself, carbon or organic materials of the type of wood sawdust, it being possible also to dilute the sulfuric acid at minimum temperatures of forty-five or fifty degrees Be. and making himself immediately blow through it air or another equivalent gas to obtain the same result.
