DRESSING SLUICE Russian patent published in 2011 - IPC B03B5/70 

FIELD: technological processes.

SUBSTANCE: invention relates to the area of gravity dressing of minerals, in particular, to devices for separation of materials in water by density, and may be used to separate complex ores that contain powdered and plate metals and minerals. A sluice for gravity dressing of minerals in a movable water flow is made in the form of at least one pipe with longitudinal section in the form of a sinusoid wave, which is inclined to the horizontal line and is connected with its upper end to a source of pulp, and with its lower end - to a facility for discharge of mill tailing into a dump. At the upper point of upper half-waves of the pipe there is a rectilinear section. The lower half-waves, which are the cells for collection of concentrate, have a loosening mechanism and a facility for discharge of concentrate.

EFFECT: increased efficiency of heavy fraction minerals extraction and separation of each single mineral fraction in a specific fixed section of the sluice, and also increased productivity and simplicity in design and maintenance.
