APPARATUS OF THE GRAVITATIONAL ENRICHMENT OF THE MINERALS Russian patent published in 2007 - IPC B03B5/70 

FIELD: mining industry; devices for the gravitational enrichment of minerals.

SUBSTANCE: the invention is pertaining to the field of mining industry, in particular, to the gravitational methods of enrichment and may be used for enrichment of the materials containing the noble metals. The apparatus for the gravitational enrichment in the fine layer of the water contains the chute made in the form of the descending spiral with the V-shaped bottom, the system of feeding of the aerated water, the tanks for collection of the concentrate and tailings located in the end of the chute. At that the apparatus has the body made in the form of the pyramid with the steps formed by the chute in the form of the descending spiral with the V-shaped bottom. The system of the aerated water feeding is made in the form of the flexible perforated pipe laid as the spiral at the vertical walls of the steps. The technical result of the invention is the increased efficiency of the minerals separation.

EFFECT: the invention ensures the increased efficiency of the minerals separation.
