(54) METHOD OF ENRICHMENT OF MINERAL RESOURCES

This invention relates to a process for the beneficiation of minerals and minerals in production, for example, with separation of coarse-grained materials, f

The HsBecT fi method of dividing secondary secondary k, for example, a metallic cicpana into components, concludes (f1cc) separating the source material supplied to the first layer - granules from the liquid in the water of the material, directed to the surface of the moving water flow 1.

However, the known method has the following flaws: a) the impossibility of separating minerals of the same or similar specific gravity or size of single pieces; b) the impossibility of separating a heavy mineral in an aqueous medium into an upper product, such as metal sulfide, and a light one - into the lower one.

The aim of the invention is to expand the size range of the material to be divided with the same and close specific weights of the components.

This is achieved by pretreatment of the starting material with selectively acting reagents with the collector. :

The method is carried out as follows. In a separate cycle, hydrophobic floating granules-pontoons of appropriate sizes are prepared. The apparatus enters water before filling. And overflow through the overflow threshold.

In the course of the latter’s movement, an even layer of granules from a material not sinking in water (pontoons) is firstly loaded into the device and then an equal stream is fed, previously treated with a selectively acting reactivator, the source material.

The layer of non-stray granules under the substance of the material bends and partially goes into the water.

Hydrophilic minerals drown, wereted across the interiors, and the hydrophobic ones are transported by the pontoons to the concentrate receiver, where they are released by gentle mixing from the pontoons, which return

5 in the head process. Then the cycle repeats.

The proposed method was tested under laboratory conditions when separating mixtures of graphite-quartz and quartz-cal0

cit. Oles coarsely divided into electrode graphite (–20 + 5 km) is preliminary & they are treated with reagents (a mixture of tall oil with kerosene and sour in relation to 2j3j5, an abundance consumption of 4.5 kg / t) and in 1 minute si is supplied to non-sinking wax, for example, paraffin waxed and bituminized foam granules, cork. A mixture of calcite with quartz (-10 + 1 mm) is processed with reagents, the total consumption is 0.75 kg / t

Claims (1)

water sound and magnetic fields on the liquid, pontoons, material, Techno-exonomic efficiency of the method is expressed in the following; reduced costs of grinding the waste mineral of the useful mineral; repeated use of pontoon facilities; separation possibilities are enhanced by varying the lifting force of the pontoons by their sizes, compositions, etc., the pontoon separation e can be carried out in various liquids, including those that do not have foaming properties. Claims. The method of enrichment of minerals, which consists in the separation of the source material supplied to 6926 33 a layer of granules of a non-water-melting material, directed to the surface of a moving stream of water, in order to expand the size range of the material to be divided with the same and close specific the weights of the components, the source material is pre-treated selectively acting reagent-collector.
