(54) METHOD FOR TREATMENT OF MINERAL RESOURCES

I.

The invention relates to the field of mineral processing and can be used in color, chemical and other industrial areas.

There is a method of processing minerals, which consists in grinding them in a mill with the introduction of flotation reagents into it and subsequent enrichment 1,

However, this method does not provide high enrichment rates.

The closest in technical essence to the present invention is a method of processing mineral resources, including wet grinding them in a drum mill in the presence of all or part of the reagents used in the enrichment and subsequent enrichment of the crushed material 2.

The disadvantage of this method is the large consumption of reagents with insufficiently high enrichment results.

The purpose of the invention is to increase the technological indicators of enrichment and reduce reagent consumption and enrichment processes.

To achieve this goal, the well-known method of processing minerals, including wet grinding in a drum mill in the presence of all or some of the materials used in the enrichment of the reagents and the subsequent enrichment of the crushed material, the reagent is loaded.

o located at a distance of 20-80 from the boot end.

With this method of mineral processing, the consumption is reduced.

5 reagents due to the reduction of losses when they are modified during the grinding process, technological enrichment is increased, since the reagents act on a sufficiently crushed material.

Example 1, Iron ore is crushed in a ball mill to a coarseness of 90% -0.074 mm, with e-loading

5 0.3 kg / ton of rich tall oil at a distance of 20% of the length of the drum from the start of the loading drum trunnion and 0.4 kg / ton of kerosene at a distance of 80% of it To the crushed, add 0.4 kg of glass log / t and

sulfuric acid to pH 5.5, followed by flooding of ore with four cleaners of the foam product.

Example 3. Phosphorite ore is crushed to a particle size of 40% of particles 0, 074 mm, with a load of 0.8 kg / ton of soda into grinding for a distance of 60% of the drum length from the beginning of the loading

pins. An oily tel oil is added to the crushed product. The oil is 0.7 kg / t and kerosene - 0.5 kg / t, after which the ore is floated. crushed xanthate C {, - Cd-80 g / t is added and basic copper flotation is carried out. The results of model experiments flotation of copper sulfide ore are presented in table 2.
