Abstract

Se presenta un método para separar el oro y/o la plata del cobre y otros metales contaminantes, donde se utiliza una membrana adecuada del filtro,en especial, un nanofiltro, para formar un retenato que contiene la mayoría de los complejos decian uro del metal polivalente y una infiltracion que contienela mayor parte de los complejos de cianuro del metal precioso. El proceso se aplica en especial a la recuperacion de oro y/o plata de los minerales quecontienen estos metales y uno omás met ales contaminantes. A continuacion, es posible recuperar el metal precioso de la infiltracion y el metal del complejode cianuro del metal polivalente del retenato. El metal que forma parte de cianuro polivalente disuelto se seleccionadel grup o que consiste en: Cu-Zn-Co-Fe-Ca-Mg-Pb-Ni-Cd-Hg-Pt-Pd y mezclas de éstos. Luego del paso de recuperacion, una porcion de metal precioso en el complejo de cianuro de metalprecioso monovalente se recupera por al menos una delas técnica s: cementacion, amalgamacion, precipitacion, intercambio de iones, electrolisis, adsorcion yabsorcion. El proceso comprende además: el contacto de al menos una porcion del retenato con un agente de quelato. La remocion de cianuro deretenatopara formar un retenato de cianuro agotado. La recupercion de una porcion de metal de los complejos de cianuro de metal precioso polivalente disuelto de unretenato de cianuro agotado para formar un retenato estéril y el paso de unaporcion de este u ltimo a través de un filtro para formar un segundo retenato.Incluye también el paso de al menos una porcion de retenato a través de una celda de extraccion electrolítica.
