Abstract

La presente invención se refiere a método para separar una primera especie de una segunda especie que tiene una gravedad específica diferente de la primera especie, caracterizado en que comprende las etapas de: (a) alimentar una suspensión espesa de la primera y la segunda especies hacia la artesa de un separador de espiral que tiene una pared interior y una pared exterior conectadas por un piso con lo que la suspensión espesa se forma como una banda en la cual una de las especies es concentrada y una banda exterior en la cual ésta está agotada, cuando menos una porción de la banda exterior agotada se sobrepone a la banda interior concentrada; y (b) desviar- cuando menos la parte interior de la banda agotada sobrepuesta hacia afuera en relación a la banda de concentrado subyacente en un lugar corriente arriba de un divisor.The present invention relates to a method for separating a first species from a second species having a different specific gravity from the first species, characterized in that it comprises the steps of: (a) feeding a thick suspension of the first and second species towards the trough of a spiral separator that has an inner wall and an outer wall connected by a floor whereby the thick suspension forms as a band in which one of the species is concentrated and an outer band in which it is exhausted , at least a portion of the exhausted outer band overlaps the concentrated inner band; and (b) deflect- at least the inner portion of the depleted strip overlapping outward relative to the underlying concentrate strip at a location upstream of a divider.
