Abstract

The invention relates to mining and improves leaching efficiency by improving the quality of loosening the heap and reducing the cost of its implementation. The method includes creating a hydropower base 1, installing a pile of cross-sectional hollow reinforced concrete structures across the entire area of the pile across the entire area of the square 3. In each row, the next section is chosen as a section with a smaller section of the previous section, forming a telescopic precast system. Each adjacent row is placed in the reverse order of the section relative to the previous one. On the bottom thus formed, a pile of ore material 4 is formed by dumping. Then it is irrigated with leaching agent with the reagent and the productive solutions are collected using known technology.

Description

1.13

The invention relates to mining, in particular, to methods for refining metal deposits with heap leaching.

The aim of the invention is to increase the leaching efficiency by improving the quality of loosening the heap and reducing the cost of its implementation.

Figure 1 shows the formed bottom in the plan; in FIG. 2, a heap, dumped on a shaped bottom, a vertical section.

The method of heaping; mineralization of minerals is carried out as follows.

On the waterproofing Base 1, represented, for example, by a concreted layer, a clay layer 2 is formed with a thickness of 0.03-0.05 m, which prevents the waterproofing layer from damage and reduces the friction of reinforced concrete structures. waterproofing base 1. On the formed layer of clay 2 across the strike of the future heap install hollow bc. 3 (for example, of the collector type), and in each row the next section is chosen to be smaller than the previous section, forming a telescopic precast system. Each adjacent row of railways, 3, is placed in the reverse order of the section relative to the previous one. Ore material 4 / Ore material 4 is poured onto the bottom thus formed and dumped in dumps by dump trucks and bulldozed.

After a heap has been formed, an irrigation system is placed on its upper surface in the form of perforated pipes 5, through which the ore material is irrigated with a leaching agent, such as soda. Pumping of -productive solutions is carried out using well-known technology, for example, the simplest one is by gravity on the slope of a waterproof base.

Additional loosening of the poured ore material is carried out after reducing the concentration of the useful component in the production solutions to the maximum permissible value established by the technical procedures for the leaching process.

In addition, additional loosening is done by sequential izv. treatment of reinforced concrete structures 3 of the base. Extracting gif 3 is carried out by a bulldozer to which a cable is attached; the latter is passed through the lugs in the housing block. 3. Others on the railway station in their traditional use they are intended for installation. and provided for at the factory.

After loosening, the alkalization cycle is repeated.
