Abstract

Las presentes modalidades se refieren generalmente a una tecnología para mejorar el grado de Cu/Mo mediante la adición de polímeros catiónicos como depresores selectivos para materias insolubles en ácidos, por ejemplo, silicatos y/o arcillas, en el circuito de flotación. Se ha demostrado que varios tipos de polímeros catiónicos son depresores eficaces que incluyen poliamina, poIiDADMAC, y poliacrilamida catiónica. También se describen procesos para enriquecer un mineral deseado a partir de una mena que comprende el mineral deseado y una ganga, en donde el proceso comprende llevar a cabo un proceso de flotación en presencia de uno o más depresores de polímero catiónico.
