Definitions
- Mantle, folder or cover for the distribution and/or extraction of a flow to and/or from a leach pile
- the present invention is framed in the field of mining, as well as agriculture, waste treatment, among others, areas of industry in which it is required to cover a surface and at the same time conduct and/or extract a fluid flow.
- the present invention is framed in mining activity, specifically those activities or procedures that are related to the extraction of minerals by solvents, such as heap leaching and corresponds to a sheet, film, mantle or cover to which it is attached.

- one of the processes to obtain minerals corresponds to the leaching process, where the procedure normally considers the formation of leaching piles of the mineral coming from the mine, which is reduced to a pre-established granulometry that extends over a impermeable base or surface that receives the leached solution from the pile.
- the target metal is leached by circulating a leach solution through the heap, in a procedure commonly known as percolation.
- percolation To carry out percolation, the leaching solution is distributed over the top of the pile, allowing it to infiltrate downward through the pile onto the impervious surface.
- the application dose of leaching solutions is designed to optimize the recovery of metals and minimize the consumption of chemical products, where the critical factors that influence achieving this relationship correspond to the design of the pile, the irrigation system and the climatic conditions of the site in which the pile is formed. Solution distribution uniformity is essential to maximize metal recovery.
- the heap leaching procedure has the advantage of allowing the treatment of a large amount of low-grade ore at a low cost, however it also has a series of disadvantages, since the irrigation system used considers the use of a mesh of hoses that have drippers or sprinklers, located at a predetermined distance, where said mesh of irrigation pipe is arranged above the upper surface of the pile to be leached, thereby leaving the irrigation exposed to the climatic conditions of the sector in where the pile is designed, that is, the leaching solution as well as the pile that is being watered, is subject to losses due to evaporation and losses due to wind action, among other factors that affect the leaching process.
- the drops of leaching solution are carried by the wind in the vicinity of the leaching pile, which can contaminate the environment with toxic elements, and where also due to the action of the wind and the evaporation to which the pile is subjected.
- leaching process because it is directly exposed to the environment, produces high evaporation rates, which implies a large amount of water that is used to carry out the leaching process, which implies an increase in production costs as well as damage to the environment.
- films or covers of the surface to be leached have been used that are placed above the irrigation or irrigation mesh, in order to cover the upper surface of the leaching pile with said cover and thus prevent evaporation. of the leaching solution, as well as increasing the temperature of the leaching pile, increasing the conditions for bacterial proliferation in bio-leaching procedures.
