Abstract

Un procedimiento de uso de una máquina de flotación que se utiliza en procesos metalúrgicos, espumando la máquina de flotación partículas hidrófobas de unapasta acuosa que contiene estas partículas, e incluyendo la máquina de flotación una celda (1) de flotación y un rotor (2), que se encuentra dentro de la celda de flotación y en la que el rotor se hace girar a una potencia de mezcla lo que mantiene una suspensión en lapasta y mezcla de aire con la pasta para formar espuma, y la potencia de mezcla se controla ajustando la velocidad de giro del rotor, caracterizado porque - el rotor se hace girar a la primera velocidad de giro más baja posible que, en términos metalúrgicos, se selecciona para tener una potencia de mezcla adecuada para mantener una suspensión y formar espuma y, al mismo tiempo, ser lo suficientemente pequeña como para permitir la acumulación de materia sólida en el fondo de la celda; - la cantidad de materia sólida acumulada en el fondo de la celda viene determinada; - la cantidad determinada de materia sólida se compara con un valor límite predeterminado; - si la cantidad determinada de materia sólida supera el valor límite predeterminado, la velocidad de giro del rotor se incrementa a una segunda velocidad de giro, que es más alta que la primera velocidad de giro y que es adecuada para eliminar la materia sólida acumulada en el fondo de la celda; y - se mantiene la segunda velocidad de giro, hasta que la cantidad de materia sólida esté por debajo del valor límite predeterminado, y la velocidad de giro se reduce a la primera velocidad de giro.
