Abstract

SE REFIERE A UN METODO PARA LA REDUCCION DE OXIDO DE COBRE (I) PULVERIZADO EN COBRE METALICO EN ESTADO SOLIDO POR MEDIO DE UN GAS DE REDUCCION ALIMENTADO A CONTRACORRIENTE EN UN HORNO HERMETICO DE GAS. EL HORNO ESTA EQUIPADO CON UNA CORREA SINFIN EN LA QUE SE ALIMENTA EL OXIDO QUE SE VA A REDUCIR. EL OXIDO DE COBRE (I) QUE SE ALIMENTA AL HORNO SE SECA Y CALIENTA EN LA ZONA DE SECADO Y CALENTAMIENTO, Y POSTERIORMENTE SE EFECTUA LA REDUCCION A UNA TEMPERATURA QUE OSCILA ENTRE 600 Y 900ºC EN LA ZONA DE REDUCCION POR MEDIO DE HIDROGENO. EL COBRE METALICO QUE SE FORMA, SE ENFRIA EN LA ZONA DE ENFRIAMIENTO A UNA TEMPERATURA POR DEBAJO DE 100ºC, DESPUES DE LA CUAL SE RETIRA EL SINTER DE COBRE DE LA CORREA Y SE DESCARGA DEL HORNO. TAMBIEN SE DESCRIBE UN APARATO PARA LA REDUCCION DE OXIDO DE COBRE (I) PULVERIZADO EN COBRE METALICO EN ESTADO SOLIDO POR MEDIO DE UN GAS DE REDUCCION, EL APARATO COMPRENDE UN DISPOSITIVO DE ALIMENTACION DE OXIDO DE COBRE (I), UN HORNO TUBULAR QUE ESTA EQUIPADO CON UN TUBO EXTERNO Y/O INTERNO HERMETICO A GAS Y EN EL QUE CIRCULA UNA CORREA SINFIN, ADEMAS, EL APARATO INCLUYE UN EQUIPO DE ENFRIAMIENTO, UN EQUIPO PARA RETIRAR Y DESCARGAR EL MATERIAL REDUCIDO DESDE LAS CORREAS ASI COMO UN EQUIPO PARA LA ALIMENTACION DEL GAS DE REDUCCION EN EL EXTREMO DE DESCARGA DEL HORNO Y PARA LA REMOCION DEL MISMO DEL EXTREMO DE ALIMENTACION DEL HORNO
