Abstract

Un proceso hidrometalúrgico para procesar mineral metálico que incluye una etapa oxidativa dinámica en el cual el mineral se riega con mezclas reactivas líquidas específicas, a bajas tasas de riego, para transformar progresivamente el mineral y mantener las condiciones para una recuperación mejorada del metal proveniente del mineral, mediante extracción por solvente y electroobtención. En algunas manifestaciones, los sistemas y métodos aquí descritos pueden ser usados para obtener cobre metálico a partir de la calcopirita, un mineral de cobre refractario. Una pila de cobre sometida a los regímenes electroquímicos establecidos, y mantenidos en la pila mediante estos métodos, presenta cinéticas novedosas.
