Abstract

Un proceso para la lixiviación de valores que contienen metales a partir de una mena, ó de uno ó más minerales, que no son fácilmente oxidados y que son susceptibles a reducción, comprendiendo sujetar dicha mena ó uno o más minerales a una reducción, en contacto con un medio ácido con agentes complejantes para iones sulfuros y/o ferroso, por un agente reductor ó en el compartimiento catódico de una cámara electrolítica que alienta la producción de uno ó más fases minerales que contiene metales en una forma reducida.
