Los procesos de electro-metalurgia cobran cada día mayor relevancia en la industria metalúrgica, en especial en la industria del cobre, el zinc, aluminio y otros metales, donde la producción de metales de alta pureza depende, en cada vez mayor cuantía, de la calidad y productividad de estos procesos. En el caso del cobre la demanda por el proceso de electro-refinación es creciente debido al agotamiento de los minerales oxidados y su reemplazo por minerales sulfurados que son procesados vía piro-metalurgia y posteriormente a través de un proceso de electro-refinación. Electro-metallurgy processes are becoming increasingly important in the metallurgical industry, especially in the copper, zinc, aluminum and other metals industry, where the production of high purity metals depends, in increasing amounts, on the Quality and productivity of these processes. In the case of copper, the demand for the electro-refining process is increasing due to the depletion of the oxidized minerals and their replacement by sulphured minerals that are processed via pyro-metallurgy and subsequently through an electro-refining process.
En la actualidad, existen tecnologías divulgadas de esta materia, pero su robustez estructural ha estado relacionada a dimensiones de espesor de estructura que son prohibitivas para su aplicación en muchas de las actuales celdas de electrometalurgia, y en especial en celdas de electro-refinería, donde los espacios disponibles para el posicionamiento de un sistema de estructura están en torno a los 2 a 3 centímetros entre electrodos y la pared interior de la celda, lo que impide la
utilización de una estructura como las divulgadas hasta el momento, y hace necesario un cambio de concepto en el tipo de estructura a utilizar. At present, there are disclosed technologies of this matter, but its structural robustness has been related to dimensions of structure thickness that are prohibitive for its application in many of the current electrometallurgy cells, and especially in electro-refinery cells, where the spaces available for the positioning of a structure system are around 2 to 3 centimeters between electrodes and the inner wall of the cell, which prevents the use of a structure such as those disclosed so far, and necessitates a change of concept in the type of structure to be used.

El documento CL20063001 describe un sistema modular potenciador de procesos electro-metalúrgicos, constituido por un núcleo estructural con otros módulos relacionados a él, bastidores superiores e inferiores conformados por vigas superiores e inferiores a izquierda y derecha, bastidores transversales trasero y delantero, pilares esquineros, pilares intermedios, diagonales, y opcionalmente elementos de soporte al piso de la celda, ubicados en las vigas inferiores.
El citado documento corresponde a la patente concedida el año 2009, número de registro 46208, y presenta una serie de aplicaciones industriales realizadas, en celdas de electro-deposición con ánodos de plomo y cátodos de acero inoxidable, con resultados positivos. Sin embargo, la concepción de su estructura, con vigas inferiores y vigas superiores, y pilares esquineros e intermedios, por sí misma requiere de un espacio holgado de instalación entre cátodos y ánodos, y la pared interior de la celda, lo que es factible en la mayoría de las celdas de electro-deposición existentes, pero no en la gran mayoría de las celdas de electro-refinería; y más aún, por motivos de fuerzas excesivas sobre la estructura, ligadas a errores comúnmente dados durante la operación industrial en la inserción y retiro de cátodos y ánodos, y en especial cátodos, la estructura ha debido ser reforzada con elementos estructurales adicionales, ensamblados a ésta, permitiendo la consecución de la robustez estructural requerida mediante espesores de pared del orden de los 8 a 10 centímetros, mientras que el espacio disponible para electro-refinería es del orden de los 2 a 3 centímetros, lo que la hace no aplicable. Document CL20063001 describes a modular electro-metallurgical process enhancer system, consisting of a structural core with other modules related to it, upper and lower racks consisting of upper and lower left and right beams, rear and front transverse racks, corner pillars, intermediate, diagonal pillars, and optionally support elements to the cell floor, located in the lower beams. The aforementioned document corresponds to the patent granted in 2009, registration number 46208, and presents a series of industrial applications made, in electrodeposition cells with lead anodes and stainless steel cathodes, with positive results. However, the conception of its structure, with lower beams and upper beams, and corner and intermediate pillars, by itself requires a loose installation space between cathodes and anodes, and the inner wall of the cell, which is feasible in most existing electrodeposition cells, but not in the vast majority of electro-refinery cells; and even more, due to excessive forces on the structure, linked to errors commonly given during the industrial operation in the insertion and removal of cathodes and anodes, and especially cathodes, the structure must have been reinforced with additional structural elements, assembled to this, allowing the achievement of the structural strength required by wall thicknesses of the order of 8 to 10 centimeters, while the space available for electro-refinery is of the order of 2 to 3 centimeters, which makes it not applicable.

Una serie de travesaños básales están ensamblados a las paredes verticales longitudinales, sobre su porción inferior cerrada, coincidentemente con las nervaduras verticales, dispuestos en forma transversal a la celda, y comprenden una sección transversal de "U" invertida, que termina en sus extremos de ensamblaje en superficies de brida, que son consistentes con las porciones inferiores de las paredes verticales longitudinales, en donde además cada travesaño comprende una abertura central inferior para el paso libre de electrolito y borras generadas en el proceso de electro-metalurgia, y prolongaciones verticales simétricas de su sección transversal en sus extremos, que se proyectan por debajo de la porción inferior de las paredes verticales longitudinales, en donde los travesaños básales soportan en conjunto la totalidad de las fuerzas verticales que se ejercen sobre la estructura y que son transmitidas al fondo de la celda. A lower portion of the longitudinal vertical walls, located under the horizontal ribs, is closed, and is located below the lower point of cathodes and anodes, for the transmission of vertical forces towards the basal area of the clamping structure.

At least one of the transverse vertical walls comprises in its upper part, in its own structure, or in an attached form thereto, a support for an annular rod of instrumentation, which comprises circular, partially open cylindrical vertical surfaces, and a surface horizontal flat basal, which holds the weight of the annular rod on the longitudinal vertical wall, and ensures its stability and precision in its installation height, to obtain reliable measurements of electrolyte level in the cell, temperature, conductivity, acidity, chemical sensors, turbidity and / or dissolved metal content.

El material polimérico constituyente de las paredes verticales longitudinales y transversales puede comprender un refuerzo de fibras, que le permiten una elevada resistencia a la flexión y el pandeo, que pueden ser orgánicas como el carbono o bien inorgánicas como el vidrio. The polymeric material constituting the longitudinal and transverse vertical walls can comprise a fiber reinforcement, which allows it a high resistance to bending and buckling, which can be organic like carbon or inorganic like glass.
El material polimérico constituyente de las patas puede consistir en un polímero termoestable con una carga de sólido mineral, o termoplásticos como el teflón, o PVC, que le permiten una elevada resistencia a la compresión en las condiciones de temperatura al interior de la celda.
Al menos una de las paredes verticales transversales puede comprender un elemento de soporte para el sistema de distribución de electrolito, empernado a ella, que lo estabiliza y rigidiza.
