Description

The invention relates to mining.

The purpose of the invention is to increase the efficiency of formation of technogenic deposits by accelerating the deposition of useful components.

This is achieved by that. that when implementing the proposed method, including the formation of an anti-filtration base of the dump, layer-by-layer laying of layers with different metal contents and mineral composition, the creation of an anti-filtration layer and bridges, and treatment of the surface of the dump with leaching solutions, an enriched layer of rocks is formed on the anti-filtration base of the dump with a relatively high metal content, the sides of this layer (rus) are shielded by an antifiltration layer, and a perforated network is formed on the surface pipeline, after which they form an antifiltration layer — a base, on which a perforated pipeline is also laid, the pipelines of these two layers are interconnected by a loading and magnetizing device, then a leachable layer with a relatively low metal content is formed, the sides of which are also shielded .

During the storage of rocks, water is supplied to the surface of the second bed (layer). The dissolution of useful components from the rocks of this layer occurs. The solutions enter the perforated pipeline, then into the loading device, and from there into the enriched rus, where useful components are deposited.

The proposed method is illustrated in the drawing.

The method of implementation as follows,

A rock layer 1 with anti-filtration properties is laid as the base of the dump on the prepared site, then an enrichment layer 2 is formed, for example, of substandard ores, the side surfaces of which are covered with screens 3 of anti-filtration rocks. A perforated pipe 4 is formed on the surface of layer 2, after which an antifiltration layer 5 of the second clay bed is formed, on which a network of perforated pipe 6 is laid (in special mud beds). Pipelines 4 and 6 are connected

through boot 7 and magnetizing 8 devices.

Then, embankments 9 of the second layer of metal-containing rocks (leaching layer) are formed, the side surfaces of which are covered with shields 10 of clay rocks. If necessary, screens are formed from polyethylene films.

After the formation of the dump mass is completed, the embankments 9 are treated with solutions from the source 11, as a result, the metals contained in the rocks of the embankments 9 are dissolved. The metal-bearing solutions through pipeline 6 enter the loading device 7, where they are mixed with seed particles, the resulting mixture enters the magnetizing device 8, where the pulp is magnetized, and from there into the enriched bed, where useful components (metals) are deposited.

An example of a specific implementation of the proposed method can be the storage of carbonate-bearing rocks and substandard ores.

After planning a plot of the earth's surface, an anti-filtration base 1 of clay rocks with a thickness of 0.5 m is formed. Then an enrichment layer 2 of substandard carbonate ores with a thickness of 5 m is formed, the side surfaces of which are covered with an anti-filtration screen 3, for example, with a plastic film. On the surface of layer 2, a network of perforated conduit 4 is formed with holes down. Then, an anti-filtration layer 5 of clays with a thickness of 0.5 m is formed, and layer 5 is formed, leaving evaporation pads through which water evaporates from layer 2. Then, a perforated pipe b is formed, which is connected to the pipe 4 by means of loading 7 and magnetizing 8 devices . After that, a leachable second layer of carbonite-containing rocks with a thickness of 3-6 m is formed, the side surfaces of which are covered with a plastic film.

After that, the second layer is treated with water containing carbon dioxide from sources 11. In this case, the carbonate-containing rocks of the second layer are dissolved. Calcium sulfate solutions through a pipeline. 6 enter the loading device 7, where they are mixed with iron sulfates, presented in powder form. Then formed
