Abstract

LA PRESENTE INVENCIÓN SE REFIERE A UN PROCESO PARA EL TRATAMIENTO TÉRMICO DE UN MINERAL METALÍFERO QUE CONTIENE AZUFRE EN EL QUE EL MINERAL METALÍFERO SE CALCINA A TEMPERATURAS DE ENTRE 600 Y 1200°C EN PRESENCIA DE OXÍGENO EN UN REACTOR, DE MODO QUE ENTRE 1 Y 90% EN PESO DE AZUFRE CONTENIDO EN EL MINERAL METALÍFERO SE QUEMA A DIÓXIDO DE AZUFRE Y LAS IMPUREZAS CONTENIDAS SE EXPULSAN EN FORMA GASEOSA. EL GAS DE ESCAPE QUE SE PRODUCE Y QUE CONTIENE EL DIÓXIDO DE AZUFRE SE ALIMENTA A UNA PURIFICACIÓN DE GAS QUE COMPRENDE POR LO MENOS UN COMPONENTE Y/O EL MINERAL CALCINADO SE ALIMENTA EN POR LO MENOS UNA ETAPA DE PROCESO ADICIONAL. UN GAS DE ESCAPE DE LA PURIFICACIÓN DE GAS Y/O LA ETAPA DE PROCESO Y/O UN GAS UTILIZADO PARA ENFRIAR DENTRO DE LA PURIFICACIÓN DE GAS O PARA ENFRIAR DENTRO DE UNA ETAPA DE PROCESO ADICIONAL SE DEVUELVE POR LO MENOS PARCIALMENTE AL REACTOR COMO GAS DE RECICLAJE QUE TIENE UNA TEMPERATURA DE > 100°C.THE PRESENT INVENTION REFERS TO A PROCESS FOR THE THERMAL TREATMENT OF A METALYPHER MINERAL CONTAINING SULFUR IN WHICH THE METALLYPHER MINERAL IS CALCINATED AT TEMPERATURES FROM 600 TO 1200 ° C IN THE PRESENCE OF OXYGEN IN A REACTOR, IN A MODE THAT ENTERS 1 90% IN SULFUR WEIGHT CONTAINED IN THE METALYPHER MINERAL IS BURNED TO SULFUR DIOXIDE AND THE IMPURITIES CONTAINED ARE EXPULSED IN GASEOUS FORM. THE EXHAUST GAS THAT IS PRODUCED AND CONTAINING THE SULFUR DIOXIDE IS SUPPLIED TO A GAS PURIFICATION THAT INCLUDES AT LEAST ONE COMPONENT AND / OR THE CALCINED MINERAL IS SUPPLIED AT LEAST ONE ADDITIONAL PROCESS STAGE. AN EXHAUST GAS FROM THE GAS PURIFICATION AND / OR THE PROCESS STAGE AND / OR A GAS USED TO COOL WITHIN THE GAS PURIFICATION OR TO COOL WITHIN AN ADDITIONAL PROCESS STAGE IS RETURNED AT LEAST TO THE REACTOR AS GAS RECYCLING THAT HAS A TEMPERATURE OF> 100 ° C.
