Abstract

La invencion describe un proceso para la concentracion de una suspension acuosa de particulas solidas, que comprende las etapas de: la introduccion de la suspension acuosa de particulas solidas en un recipiente, la adicion de al menos un floculante polimerico organico a la suspension acuosa de particulas solidas, formandose con ello solidos floculadas, permitir que los solidos floculados se asienten de manera de formar un lecho de solidos en suspension en el extremo inferior del recipiente, hacer fluir el lecho de solidos desde el recipiente como un flujo inferior, en donde una porcion del lecho de solidos o del flujo inferior es transferida en forma de una corriente de reciclado hacia el recipiente en o por arriba del lecho de solidos, en donde se anade al menos un agente activo a los solidos en la corriente de reciclado, y en donde el por lo menos un agente activo se selecciona de entre el grupo que consiste en agentes de radicales libres, agentes oxidantes y agentes reductores
