Abstract: Provided is a novel method and system for recovering aggregate fine size particles from a carrying medium. The method comprises:(a) introducing a feed containing particles to a sand screw, and separating the particles into separate groups of large and fine particles, the fine particles being present in a fine particle stream;(b) introducing the fine particle stream from the sand screw to one or more hydraulic centrifugal separators which overflow a fine particle stream and discharge a coarse particle stream;(c) introducing the overflow fine particle stream from the one or more hydraulic centrifugal separators to a thickening tank and removing precipitated material as an underflow stream from a lower portion of the thickening tank; and(d) introducing the underflow from the thickening tank to a filtering unit.
