Abstract

La presente invencion se refiere a un metodo para recuperar selectivamente un mineral a partir de una mena al aplicar un promotor que es etilendiamina sustituida. Ademas, la presente invencion se refiere al uso de dicha alquilendiamina polimerica sustituida para separar un mineral objetivo de una mena. Este metodo comprende las siguientes etapas: i) moler la mena; ii) preparar una pulpa de la mena molida obtenida en la etapa i); iii) agregar al menos un promotor que comprende al menos una alquilendiamina polimerica sustituida a la pulpa obtenida en la etapa ii); iv) someter la pulpa que contiene el promotor obtenida en la etapa iii) a flotacion de espuma.
