Abstract

Apparatus and method for separating intermixed particles of differing densities including a separator bowl rotatable about an axis inclined to the horizontal plane and having a base wall and a peripheral wall, and a plurality of radially-spaced chambers disposed around the peripheral wall and extending from adjacent the base wall to the upper edge of the peripheral wall, each of the chambers having chamber walls converging with one another away from the axis to a discharge port at a height intermediate the base wall and the upper edge. The bowl is rotated and a mixture of the particles is fed into the lower portion of the bowl and the mineral particle fraction discharged from the discharge port of the bowl is collected.
