Abstract

Se describe un metodo de tratamiento de aguas de proceso de una planta de flotacion (1). La planta de flotacion (1) comprende una linea de flotacion de minerales (10) y un circuito de agua de proceso (20) para el tratamiento de desbordamiento y/o subdesbordamiento de la linea de flotacion. El circuito de agua de proceso comprende un separador gravitacional solido-liquido (21) para desaguar el desbordamiento y/o el subdesbordamiento de la linea de flotacion de minerales para separar el sedimento (212) del sobrenadante (211) que comprende al menos agua y particulas finas no recuperadas que comprenden material valioso; y un tanque de recuperacion de agua (25) para recolectar agua de proceso (500). Segun el metodo, antes de conducir el sobrenadante (211) del separador gravitacional solidoliquido (21) al tanque de recuperacion de agua (25), se somete a flotacion de limpieza, en donde al menos el 90% de las burbujas de gas de flotacion tienen un tamano de 0.2 a 250 micromol, en una unidad de flotacion de limpieza (23). Tambien se describen una mecanismo para tratar las aguas de proceso de una planta de flotacion y su uso
