Abstract

PROCEDIMIENTO PARA LA OBTENCION DE DIOXIDO DE AZUFRE POR DISOCIACION TERMICA DE SULFATOS METALICOS Y TOSTACION SIMULTANEA DE PIRITAS.LOS SULFATOS METALICOS Y LAS PIRITAS SE GRANULAN CONJUNTAMENTE Y LUEGO SE INTRODUCEN EN EL REACTOR. COMO SULFATOS METALICOS PREFERENTES SE UTILIZAN LAS TORTAS DE FILTRACION CON ACIDO ADHERIDO QUE SE GRANULAN PREVIAMENTE Y LUEGO SE REVISTEN CON SULFUROS METALICOS. ES VENTAJOSO UTILIZAR PIRITAS DE FLOTACION CUYO TAMAN/O DE PARTICULAS SE SITUE POR DEBAJO DE 0,1 MM.
