Abstract

Se refiere a un proceso metalurgico para la extraccion continua de metales ferrosos y no ferrosos a partir de minerales sulfurados que los contienen, el cual esta conformado por un proceso de extraccion de metales en un horno de fundicion de concentrado de minerales, asi como por procesos de disolucion de escoria y filtrado de residuos, regeneracion del carbonato de sodio en un reactor de soluciones, eliminacion del gas sulfhidrico y obtencion de azufre, sinterizacion de aglomerados de oxido de hierro, generacion de gases reductores en el horno de combustion, y regeneracion del agente reductor hierro para su reciclaje. Con ello se establecen mecanismos de control estequiometrico de las reacciones quimicas de extraccion de metales a partir de los minerales sulfurados que los contienen, es decir en cuanto a las cantidades de hierro y carbonato de sodio requeridos como reaccionantes del proceso, de modo de tener un control efectivo sobre las cantidades de oxido de hierro y sulfuro de sodio como componentes de la escoria
