Abstract
Se describe un método de tratamiento de aguas de proceso de una planta de flotación (1). La planta de flotación (1) comprende una línea de flotación de minerales (10) y un circuito de agua de proceso (20) para el tratamiento de desbordamiento y/o subdesbordamiento de la línea de flotación. El circuito de agua de proceso comprende un separador gravitacional sólido-líquido (21) para desaguar el desbordamiento y/o el subdesbordamiento de la línea de flotación de minerales para separar el sedimento (212) del sobrenadante (211) que comprende al menos agua y partículas finas no recuperadas que comprenden material valioso; y un tanque de recuperación de agua (25) para recolectar agua de proceso (500). Según el método, antes de conducir el sobrenadante (211) del separador gravitacional sólido-líquido (21) al tanque de recuperación de agua (25), se somete a flotación de limpieza, en donde al menos el 90% de las burbujas de gas de flotación tienen un tamaño de 0.2 a 250 μm, en una unidad de flotación de limpieza (23). También se describen una mecanismo para tratar las aguas de proceso de una planta de flotación y su uso.A process water treatment method of a flotation plant (1) is described. The flotation plant (1) comprises a mineral flotation line (10) and a process water circuit (20) for the treatment of overflow and/or underflow of the flotation line. The process water circuit comprises a solid-liquid gravitational separator (21) to dewater the overflow and/or underflow of the mineral waterline to separate the sediment (212) from the supernatant (211) comprising at least water and unrecovered fine particles comprising valuable material; and a water recovery tank (25) for collecting process water (500). According to the method, before leading the supernatant (211) from the solid-liquid gravitational separator (21) to the water recovery tank (25), it is subjected to cleaning flotation, where at least 90% of the gas bubbles of flotation have a size of 0.2 to 250 μm, in a cleaning flotation unit (23). A mechanism for treating the process waters of a flotation plant and its use are also described.
