Abstract

This invention relates to the beneficiation of minerals. The goal is to increase productivity by accelerating the stratification of materials in terms of density. The table supports are fitted with deck 1 with aerators 2 and longitudinal riffles 3, made with horizontal protrusions in the upper part. The projections are directed towards the device 5 for supplying flush water. The movements of deck 1 are carried out by longitudinal 6 and 7 transverse vibration drives. The pulp is continuously jetted to the receiving tray 4 and then to deck 1. Moving on deck 1, the light fraction is rinsed off by flushing water from tool 5. High-density minerals continue to move along flute 3 where they come in contact with dispersed air created by the aerator 2. When the table is transversely worn, the material under the ridge of the grooves separates. 3. With simultaneous and longitudinal vibration of the table, the difference between the angles of the washout increases significantly. This significantly speeds up the separation process. 2 Il.

Description

Fig. /

The invention relates to the enrichment of minerals and can be used in the combination of gravitational enrichment with flotation in the presence of air, carried out on concentration tables,

The purpose of the invention is to increase productivity by accelerating the separation of minerals in density,

FIG. 1 shows a flotation gravity concentration table; in fig. 2 shows section A-A in FIG. one.

Flotation Gravity Concentration Table includes deck 1 installed on supports with simultaneous longitudinal and transverse movement with aerators 2 and longitudinal grooves 3, tray 4, fixture 5 for feeding water, longitudinal 6 and transverse 7 vibratory drives for moving the deck, Riffly 3 is made with horizontal protrusions 8 in the upper part, directed towards the device 5 for supplying flush water.

The device works as follows.

Previously, in the contact tank with reagents, processed pulp is continuously fed into the receiving tray 4 and then to the deck 1 of the table. Moving on deck 1, the light fraction is flushed off by flushing water from tool 5, and minerals with a high specific gravity continue to move along flute 3, where they come into contact with the dispersed air created by the aerator 2. Hydrophobic minerals attach to air bubbles and As mineralized foam is washed into the light fraction, hydrophilic mineral grains with a high specific gravity continue to move along flute 3 and are discharged into the heavy fraction. When the table is transversely worn, the material under the protrusion 8 of the flute 3 separates. When the table is simultaneously transversely and longitudinally displaced, the difference between the flush angles increases significantly, which significantly speeds up the separation process. This circumstance makes it possible to increase the tilt angle of the table and the amplitude of the longitudinal stress, as a result of which the productivity increases.
