Abstract

La presente descripcion proporciona un metodo para mejorar la recuperacion de oro en un circuito de lixiviacion con cianuro que comprende una pulpa de mineral aurifero. El metodo comprende la etapa en que se suministra un aditivo de recuperacion de oro elegido entre acido poliacrilico, copolimeros de acido acrilico y un comonomero sulfonado, asi 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 metodo tambien comprende la etapa en la que se combina el aditivo de recuperacion de oro con la pulpa de mineral aurifero en el circuito de lixiviacion con cianuro, en donde el aditivo de recuperacion de oro esta presente en una cantidad de alrededor de 10 a alrededor de 1000 g por tonelada de mineral aurifero seco para mejorar la recuperacion de oro de la pulpa de mineral aurifero.
