Abstract
La presente descripción proporciona un método para mejorar la recuperación de oro en un circuito de lixiviación con cianuro que comprende una pulpa de mineral aurífero. El método comprende la etapa en que se suministra un aditivo de recuperación de oro elegido entre ácido poliacrílico, copolímeros de ácido acrílico y un comonómero sulfonado, así como combinaciones de estos componentes, en donde el aditivo tiene un peso molecular promedio de alrededor de 500 a alrededor de 10,000 g/mol. El método también comprende la etapa en la que se combina el aditivo de recuperación de oro con la pulpa de mineral aurífero en el circuito de lixiviación con cianuro, en donde el aditivo de recuperación de oro está presente en una cantidad de alrededor de 10 a alrededor de 1000 g por tonelada de mineral aurífero seco para mejorar la recuperación de oro de la pulpa de mineral aurífero.
