GRAVITY MINERAL DRESSING DEVICE Russian patent published in 2014 - IPC B03B5/62 

FIELD: mining.

SUBSTANCE: gravity mineral dressing device comprises a loading hopper conjugate to the distribution chamber, from both sides of the chamber the slope upward and downward dividing transporting channels are mounted, which contain with a possibility of change of the spatial position the lapping plates with cross partitions, and also slope unloading channel with the device for transportation of dispersed mineral matter implemented as an elevator. The bottom part of the unloading channel is hydraulically connected with the bottom of the downward transportation channel. The device is fitted with a tank with the bleeding line, inside which an opened vessel for running water connected to the unloading channel with elevator is located. The unloading channel is fitted with a water level regulator, which is implemented as a vessel, where with a possibility of movement in a vertical direction the tubular control vertical branch pipe connected with a free-flow bleeding line is installed. In the water level regulator a sensor connected to a transporter drive, feeding mineral material into the loading hopper is installed. The upper end of the tubular control vertical branch pipe is implemented bevelled or fitted with a drainage cut. The upper edge of the open vessel is located below the upper edge of the tank.

EFFECT: improvement of quality of dressing process, minimising losses of minerals.
