Abstract

Las realizaciones incluyen sistemas y metodos para molienda en etapas multiples de material mineral triturado. Un metodo puede comprender separar, en una primera etapa de separacion, material mineral triturado por tamano en una primera corriente de finos y una primera corriente gruesa; moler la primera corriente gruesa en una segunda etapa de molienda; alimentar el producto de la segunda etapa de molienda nuevamente a la etapa de separacion; alimentar la primera corriente de finos de la etapa de separacion a un circuito de recuperacion; producir una corriente rechazada del circuito de recuperacion de material mineral triturado que no cumple con el tamano mineral objetivo; separar, en una segunda etapa, la corriente rechazada del circuito de recuperacion en una segunda corriente de finos y una segunda corriente gruesa; moler la segunda corriente gruesa en una tercera etapa de molienda; y alimentar el producto de la tercera etapa de molienda nuevamente al circuito de recuperacion.
