Abstract

El invento que tiene por título “Proceso para extraer metales a partir de los concentrados de minerales sulfurados que los contienen aplicando reducción directa con regeneración y reciclaje del agente reductor hierro y del fundente carbonato de sodio” se presenta como una alternativa a los procesos convencionales de extracción de metales ferrosos y no ferrosos a partir de los minerales sulfurados que lo contienen, aplicando el proceso de reducción directa mejorado, esto es, sin emisiones de anhídrido sulfuroso y sin producir las escorias que genera la metalurgia convencional, minimizando así la contaminación ambiental. Además, mediante la regeneración y reciclaje del agente reductor hierro y del fundente carbonato de sodio, se reducen sustancialmente los costos operativos del proceso metalúrgico.
