Abstract

Las presentes modalidades se refieren generalmente a una tecnologia para mejorar el grado de Cu/Mo mediante la adicion de polimeros cationicos como depresores selectivos para materias insolubles en acidos, por ejemplo, silicatos y/o arcillas, en el circuito de flotacion. Se ha demostrado que varios tipos de polimeros cationicos son depresores eficaces que incluyen poliamina, poliDADMAC, y poliacrilamida cationica. Tambien 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 flotacion en presencia de uno o mas depresores de polimero cationico.
