Abstract

Un procedimiento de obtener tres productos de material fragmentario que tiene productos de tres pesos específicos distintos, por medio de un agente pesado, consistente en una suspensión de sólidos de alto peso específico finamente divididos en un líquido; que comprende introducir el material a separar junto con agente de complemento en un charco alargado en forma de cuña del agente pesado en el extremo profundo del mismo y debajo de la superficie, mantener por medio de un transportador mecánico un movimiento diagonal de una columna de agente pesado desde el punto del charco de agente al extremo de menos profundidad, siendo la columna de sección considerable en comparación con la sección máxima del charco; descargar el material de peso específico mínimo desde el nivel del charco en un punto a considerable distancia sobre la columna de movimiento diagonal, descargar material de sedimento del extremo de poco fondo del charco por transporte mecánico; descargar los medios de la superficie del charco en un punto contiguo a la columna movida mecánicamente, estando el punto de introducción de la carga contiguo al borde superior de la columna movible y ajustar la velocidad de movimiento de dicha columna, el movimiento predominantemente horizontal del agente desde la entrada de carga al punto de descarga de al flotación y los medios de manera que la resultante de estas fuerzas con la flotabilidad de los productos de flotación produce una trayectoria de partículas de flotación en promedio desde la entrada de carga al punto de descarga de al flotación y una trayectoria de partículas medias en promedio desde la entrada de carga al punto de descarga de los medios.A process of obtaining three products of fragmentary material having products of three different specific gravities, by means of a heavy agent, consisting of a suspension of finely divided high specific gravity solids in a liquid; which comprises introducing the material to be separated together with the complement agent in an elongated wedge-shaped puddle of the heavy agent at the deep end thereof and below the surface, maintaining by means of a mechanical conveyor a diagonal movement of a column of agent weighed from the point of the agent pool to the shallow end, the column being of considerable section compared to the maximum section of the pool; discharging the material of minimum specific gravity from the puddle level at a point at considerable distance on the diagonal moving column, discharging sediment material from the shallow end of the puddle by mechanical transport; discharge the media from the surface of the puddle at a point adjacent to the mechanically moved column, the point of introduction of the load being contiguous to the upper edge of the movable column and adjust the speed of movement of said column, the predominantly horizontal movement of the agent from the load inlet to the discharge point of the float and the means so that the resultant of these forces with the buoyancy of the flotation products produces a trajectory of flotation particles on average from the load inlet to the discharge point of to buoyancy and a mean particle path on average from the charge inlet to the media discharge point.
