Abstract

EN DONDE UN CONCENTRADO DE COBRE, UN FLUJO Y UN GAS DE REACCION SE ALIMENTAN JUNTOS EN LA CHIMENEA DE REACCION DE UN HORNO DE FUNDICION EN SUSPENSION, DONDE SE CREAN FASES SEPARADAS, ES DECIR EL COBRE BLISTER Y LA ESCORIA. EL METODO SE CARACTERIZA PORQUE: A) LA ESCORIA DEL HORNO DE FUNDICION EN SUSPENSION SE CONDUCE A UN HORNO ELECTRICO; B) LA ESCORIA SE TRATA EN UN HORNO ELECTRICO CON UN AGENTE DE REDUCCION, TAL COMO COKE, DE TAL FORMA QUE EN EL HORNO ELECTRICO SE CREAN FASES SEPARADAS, ES DECIR EL METAL DE FONDO Y LA ESCORIA DE DESECHO; C) EL METAL DE FONDO DEL HORNO ELECTRICO ES REMOVIDO DEL HORNO ELECTRICO; D) EL METAL DE FONDO DEL HORNO ELECTRICO ES GRANULADO POR AGUA, Y SE OBTIENE METAL DE FONDO DEL HORNO ELECTRICO GRANULADO; Y E) EL METAL DE FONDO DEL HORNO ELECTRICO GRANULADO SE ALIMENTA A LA CHIMENEA DE REACCION DEL HORNO DE FUNDICION EN SUSPENSIONWHERE A COPPER CONCENTRATE, A FLOW AND A REACTION GAS ARE FEED TOGETHER IN THE REACTION CHIMNEY OF A SUSPENSION CASTING OVEN, WHERE SEPARATE PHASES ARE CREATED, THAT IS, THE COPPER BLISTER AND THE SLAG. THE METHOD IS CHARACTERIZED BECAUSE: A) THE SLAG FROM THE SUSPENSION CAST OVEN IS CONDUCTED TO AN ELECTRIC OVEN; B) THE SLAG IS TREATED IN AN ELECTRIC OVEN WITH A REDUCTION AGENT, SUCH AS COKE, IN SUCH A WAY THAT SEPARATE PHASES ARE CREATED IN THE ELECTRIC OVEN, THAT IS, THE BACKGROUND METAL AND THE WASTE SLUG; C) THE BOTTOM METAL OF THE ELECTRIC OVEN IS REMOVED FROM THE ELECTRIC OVEN; D) THE BOTTOM METAL OF THE ELECTRIC OVEN IS GRANULATED BY WATER, AND BOTTOM METAL IS OBTAINED FROM THE ELECTRIC OVEN GRANULATED; AND E) THE BOTTOM METAL FROM THE GRANULATED ELECTRIC OVEN IS FEEDED TO THE REACTION CHIMNEY OF THE SUSPENSION CAST OVEN
