ABSTRACT:
The invention consists of an upright tank structure that includes axially aligned first and second tank parts, the first tank part being smaller in diameter than the second part. A first horizontal barrier plate having holes therethrough is mounted in the first tank part between upper and lower regions of the same. A second annular barrier having holes therethrough is mounted between the side walls of the first and second tank parts between upper and lower regions. Feed slurry is introduced into the upper region of the first tank part. Water under pressure is introduced into the region below both the first and second barriers and is caused to flow upwardly through the openings of the barriers with the formation of water jets extending upwardly from the openings. In operation the solids of the feed slurry are separated into coarse, fine and intermediate or middling fractions. The invention includes both apparatus and a method of operation.
