COVER FOR COVERING SURFACES

Field of the invention.

The present invention is framed within agriculture field, such as relates to plasticulture, mining, waste treatment, to each others, industries areas in which is required surface cover and at the same time driving or removing a gas, air and/or fluid stream, such as solutions, water, among others, in particular in the field of the surfaces covers on which it is necessary delivering, distributing or removing a fluid, gas or air flow, whose configuration also makes posible to able monitoring and/or controling the cover surfaces conditions, as well as conditions of the gas, air and/or fluid flow removed, delivered and/or distributed by said cover. Preferably the present invention is fra med within the mining activity, specifically those activities or processes in relation with the solvents minerals extraction, such as stack leaching, as well as the present invention is part of the plasticulture, and / or in the industrial and / or domiciliary waste management activity.

BACKGROUND OF THE INVENTION

In the mining area, one of the processes to obtain minerals corresponds to the leaching process, where the process normally considers the mineral leaching piles formation coming from the mine, which is reduced to a pre-established granulometry, and extends on a waterproof base or surface, which may comprises plastic film sheet. The crushed material is mounted on the surface to form large ore crushed piles to be leached. Once the pile has been prepared, the target metal is leached by circulating a leach solution through the pile, in a process commonly known as percolation. To carry out the percolation, the leaching solution is distributed over the pile top, allowing it to infiltrate down through the pile into the impermeable surface.

There are a number of known options for distributing the leach solution on the top surface of a pile. The options that are generally used correspond to the solution pulverizing or spraying systems on the pile upper surface or drip systems, which is achieved by mounting an irrigation mesh on the pile surface to be leached.

The application leaching solutions rate are designed to optimize the metals recovery and minimize the chemical products consumption, where the critical factors that influence in achieving this relationship correspond to the pile design, the irrigation system and the site climatic conditions in which the pile is formed. The uniformity of the solution distribution is essential to maximize the metal recovery.

-1The heap leaching process has the advantage of allowing a low grade ore large quantity treatment at a lower cost, however it also has a series of disadvantages, since the irrigation system used considers the use of a mesh hoses with drippers or sprinklers located at a predetermined distance, where said irrigation pipe mesh is disposed above the pile upper surface to be leached, with which the irrigation is exposed to the sector climatic conditions where the pile is designed, that is, the leaching solution as well as the pile that is being irrigated, is subject to losses due to evaporation and wind action, and among other factors that affect the leaching process. Leaching solution dropts are carried by the wind in the Leach pile vicinity, which can contaminate the environment with toxic elements, and where also by the wind action and evaporation to which the leaching pile is subjected, when is directly exposed to the environment, produces high evaporation rates, which produces a large water amount used to carry out the leaching process, increasing the production costs and environment damage. Another important factor to consider, where evaporation also causes heat loss, which lowers the leaching solution temperatura and the chemical leaching lowering reaction rate. The leaching solution when exposed to sunlight on a large surface increases the photochemical degradation potential of photo sensitive leaching compounds, which leads to a decrease in leaching results.

At present in the technique have been used surface films or covers to leaching that are arranged over the irrigation orirrigation mesh, so as to cover the heap leach upper surface with said cover and avoiding the leachind solution evaporation, as well as increasing the leaching heap temperature and increasing the bacterial proliferation conditions in the bio-leaching processes. Notwithstanding the foregoing, these solutions have produced a great advantage in managing the leaching solution evaporation parameters, reducing the water use rate and leaching agents, as well as increasing the Leach pile temperature, the film disposition operation on the heal leach upper surface, involves a large amount labor used, as well as time required for its disposal and fixation, so as not to be affected or dragged said film or covers of the heap leaching surface by wind action.

The leach piles can be large and extensive enough, requiring a large number of qualified personnel to monitorand control the leaching process, however, nowadays in the technique a series of systems and procedures have been developed to monitor the leaching rate, irrigation, saturation zones, fluid flow in the irrigation mesh, humidity, evaporation and temperature of the leach pile, however, these systems consider the use of a plurality devices, sensors, cameras, among other equipment, which must be placed in the entire extension of a heap leach large surface area, which leads to a large skilled labor quantity to provide a leaching pile with an automated monitoring and control system.

Another field in which covers are used for land surface, is in the agriculture, where the relationship between plastics and agriculture is so narrow that has led to plasticulture or agroplasticulture, which involves the polymers use in the agricultural production, through soil mulches, irrigation system, meshes, tunnels, greenhouse and / or covers, which allow to advance crops, out of season fruits grow, weeds and insects control, as well as water, fertilizers and soil improve

-2efficiency use. The use of quilts or mats to cover the soil surface in agricultural production is a procedure and production system that is increasing in the world. Traditionally said mats are formed by a film, where at each certain distance between rows and row a hole is practiced to leave a free space of the covered surface on which said mat is arranged, where is cultivated a plant or a tree, and where also on or under the mat are arranged a series of irrigation pipes, where sprinklers or drippers coincide with the hole made in the mat, where the plant is grown. Between rows an inert substrate is generally arranged, as a means of supporting the mat against the surface on which it is arranged.

Another field in which covers are used for land surface, are in the residential area and / or industrial waste management, such as landfills, where there is a worldwide trend is to handle landfills efficiently and ecologically sanitary, avoiding that the leaching flows that are produced by the waste decomposition, contaminate the groundwater, as well as the methane or gas that is produced by the waste decompositione collected in piles, can be used for the energy generation. For the sanitary landfill implementation it is necessary to provide a series of impermeable and / or permeable membranes for handling different leached fluids as well as to be able also provide a pile resistance, as well as being equipped with a pipes series for incorporating and / or removing air or gas in the piles, as well as incorporating and / or removing fluid in the piles, such as water, leachates, solutions, among others. One of the frequent problems in the lanfill pile handling is related to the gas loss that is normally produced by the pile surface covers, which should be as impermeable as possible, which leads to the environment contamination with gas that is produced by the pile decomposition.

The surfaces covers as defined and used in the mining, agricultura, landfill and/or industrial landfills areas have the deficiency that requires a large amount of time in work and control to achieve both the delivery system , distribution and / or removal of a fluid as covers on the surface to be covered, which implies in an operation that although it is true provides a system that allows to regulate the covered surface conditions, such as evaporation, temperature, humidity, weed control, gas control, air control, fluid removal, among others, however its implementation is high cost, product of the labor required for its installation as well as the time involved in its implementation, which also adds the time and skilled labor that is required to implement a monitoring and control system of the surface covered by said mat or film.

Therefore, there is a need in the art to be able to have a layer, cover, mat and / or film, whose configuration includes in an integrated single piece a delivery, distribution and / or fluid removal system, as well as a covered surface monitoring and control system, which are integrated in the cover, in such a way that by the mere fact that said cover, layer, mat and/or film is deployed and / or arranged, at the same time it is deployed, disposed and implemented a delivery, distribution and / or fluid removal (air, gas, water, solvents) system, and a automatic monitoring and control system of the environmental parameters and / or the integrated operation system of the surface cover.

The holes pattern that is formed by the hole series in the strip (17) allows to properly distribute the fluid flow that delivered from said irrigation means (10) on the covered surface with the film (2); this allows to improve the irrigation distribution on the surface.

Application Example:

Figure N° 8 and 12 illustrate the way in which a surface cover (1) is used as an example, which in this particular case is used to cover leach piles (28), the surface cover (1) comprises a flow conduction lines (9) series, which conduct a leaching solution, comprising a irrigation means (10) serie, such as drippers, which are arranged in spaced apart from each other throughout of said flow conduction lines (9), and where the flow conduction lines (9) series are joined to the film (2) surface by using the strips (17), which comprise series of holes (26) that form a predefined holes pattern along the strip surface (17), such that said hole pattern allows homogeneously distributing the leaching solution on the leach pile (28). A series of sensors line (11) are joined to at least one of the film (2) surfaces, where said lines comprise sensors (12) that are distributed along the sensors lines, so that said sensors allows to measure by way of example the temperature and / or the humidity, among other parameters to measure, the sensor lines are joined to the film (2) surface by means of the tie strips (17) arrangement that comprise a series of openings and / or holes (26) that coincide

-9with the sensors (12), so as to leave the sensors exposed to the leach pile surface and / or exposed to the environment. The series of flow lines (9) joined to the film (2) surface, form a leaching solution irrigated or irrigated mesh, and the series of sensor lines (11) manage to define a sensors network that comprises the cover (1) integrated to it, thus allowing to irrigate, monitor and / or control the leach piles, where said sensor lines are connected to a data transmission system, which operates in a remote and autonomous manner. In each flow conduction line, such as leaching solution, a flow sensor (27) is arranged, which is connected to the remote data transmission system and to an automatic flow control valve and operated remotely. The configuration of the cover (1) as defined in a preferential way, allows to mount in a single operation a heap leaching cover, an leaching solution irrigation mesh and a pile parameters monitoring and control systems that is being leached.

The configuration of the cover (1) of the present invention allows reduced the irrigated or irrigated system with coverage installation time approximately 66%, with respect to the systems traditionally used in the technique, where the irrigation mesh is first arranged on the heap leach, then a coverage, and then a control and monitoring system, which translates into the large amounts labor used, as well as a longer time required at each installation stage, where it is not possible to maintain a homogeneity in the irrigation lines distribution, as well as in the heap leaching control and monitoring elements distribution. The factthatthe cover (1) of the present invention comprises in an integrated way an irrigation or irrigation system, and a control and / or monitoring system, allows to provide a device for heap leaching easier to install and more efficient.

By means of the orifice pattern associated to the leach solution drippers, the leaching solution can be conducted and distributed in a much more efficient and homogeneous way, where at the same time the film can produce a greenhouse effect in the leach pile, generating greater bacterial flora reproduction, thus decreasing the process cycles, increasing the temperature with respect to the conventional leaching system, decreasing the leaching solution and water evaporation rate, which reduces the water amount used , as well as leaching solution, reducing production costs and therefore making the leaching system more efficient, where through the sensors and flow sensor line, the behavior of the leach pile is monitored in real time and remotely.

In tests performed it has been possible to measure the results indicated above, so for example the temperature inside the stack covered with the cover (1) of the invention of the present application, at different depths increases between 5 to 6 degrees with respect to the heap leach without coverage, where the evaporation rate in the heap leach without coverage was an average of 10.8 It / day / m² and the heap leach evaporation rate with the cover of the present invention was at an average of 0.42 It / day / m², which means 90% in water savings and leaching solution, due to evaporation. The fact that the drippers, which includes the leaching heap irrigated or irrigated mesh flow conduction line attached to the film, allows to avoid the wind action on the pile surface, which produces a low in the drippers sulfation, thus achieving a uniform irrigation, and which is also achieved by the homogeneous irrigation system shape and distribution that is achieved by the cover arrangement with the associated irrigation system.

-10The fact that the cover includes a protective film, an irrigation mesh, a sensors mesh, and sensors associated with the irrigation grid, provide a coverage that increases the leach pile temperature, thus improving the leaching and minerals recovery process, increase the pile humidity, decrease the leaching solution amount used as well as water quantity used in the process, avoid the irrigation system sulphation, decrease the environment contamination, increase the homogeneity irrigation, and decrease the irrigation mesh and a heap leach installation time, as well as keeping the Leach pile behavior, and the leaching process and system, monitored in line, in order to react in real time and remote to correct errors, and thus maximize results, where also can keep the cover in the site instead by the weight provided by the irrigation mesh integrated into the film, preventing it from being dragged by wind action.

While the shape of the surface covering described herein constitutes a preferred inclusion of this invention, it should be understood that the invention is not limited to this precise form of surface covering, and that changes can be made therein without departing from the scope of the invention, which are defined in the appended claims.
