<p>Apparatus (10) for hydraulically separating a mixture of small size mineral particles according to different mineral densities includes principally, an inclined tubular conduit (11). The inclined conduit (11) has a bottom surface (19a) extending axially along the conduit (11) that is tilted in a second direction relative to the direction of inclination of the conduit (11); so that the bottom surface (19a) forms a low-point line (12) extending throughout the conduit (11). An upward fluid flow through the conduit (12) for processing is adjusted to move the light mineral particles (61) in upward direction by effects of the higher midstream fluid flow velocity forces, while the conduit surface effects allow the heavy mineral particles (91) to accumulate along the low-point line (12) and to move in downward direction during processing by the inherent lower fluid flow velocity forces along the conduit boundary or wall surfaces.</p> |
