1. the method for a unpowered gravity separation;

  • It is characterized in that;

    the mine tailing in ore dressing plant is sent into classification in the flushing type hydrocyclone (1);

    Ore pulp after the classification is delivered in the chute (3) through feed launder (2);

    Ore pulp forms the slide film on the flannelette blanket formula surface of chute, the heavy mineral in the ore pulp is deposited in the fine hair formula slit on flannelette blanket formula surface;

    First Preset Time stops when arriving giving the ore deposit to feed launder (2), adopts water under high pressure will be attached to the lip-deep heavy mineral of flannelette blanket formula and is flushed in the flannelette blanket concentrate hopper (4), gives the ore deposit to feed launder (2) again after flushing finishes;

    Heavy mineral in the flannelette blanket concentrate hopper (4) is added water concocting become the secondary ore pulp;

    The secondary ore pulp is delivered to the mine distributor (6) on the enrichment conical surface (7) through mineral-feeding pipe (5), mine distributor (6) fast rotational under the impact of secondary ore pulp, and the secondary ore pulp is sprinkling upon on the enrichment conical surface (7);

    On the slope of the enrichment conical surface (7), form moisture film;

    Heavy mineral is attached on the slope of the enrichment conical surface (7), when second Preset Time arrives, stops in mine distributor, to send in (6) the secondary ore pulp.
