Abstract
Se diseña e implementa un prototipo semindustrial de aplicación y control de
microondas pulsadas para inducir fragmentación en minerales. El desarrollo del
prototipo se encuentra dentro del proyecto FONDEF IDeA N° CA13I10353: “Prototipo
de laboratorio para inducir la fragmentación de minerales vía la aplicación continua de
pulsos de microondas”, que está realizando la Universidad Técnica Federico Santa
María. El proyecto tiene por objetivo cubrir las etapas de diseño, implementación y
evaluación de un sistema de microondas pulsadas de alta densidad de potencia que
permita la generación de grietas o fracturas en los minerales para facilitar la extracción
de material. Finalmente, se busca que el proceso genere ahorros importantes a nivel
energético entre el proceso de chancado y molienda.
El equipo a desarrollar debe considerar un ingreso continuo o semicontinuo de
mineral para cumplir las características de procesamiento semindustrial, destacando
una aplicación segura, eficiente y eficaz de las microondas en las muestras de minerales
a tratar, con la finalidad de inducir la fragmentación deseada. Las etapas de desarrollo
consideran la elección de un sistema de microondas acorde al presupuesto del proyecto,
junto al diseño y evaluación de cámaras de aplicación de microondas que aseguren un
tratamiento uniforme y eficiente, asegurando que gran parte de la potencia entregada
sea absorbida por la muestra. Posteriormente, se contempla el desarrollo del sistema de
ingreso de minerales de forma continua o semicontinua, logrando que el prototipo sea
adecuado para niveles industriales o de laboratorio, permitiendo un alto volumen de
procesamiento de minerales por unidad de tiempo.
Finalmente, si los resultados anteriores son satisfactorios, se espera poder llevar
estos avances a equipos de mayores niveles de potencia, de forma tal de generar un
impacto real en el ámbito del procesamiento en la minería. Sin embargo, para poder
realizar lo anterior serán necesarios más recursos a nivel económico y de investigación.
It is designed and implemented a semi-industrial prototype for control of microwave pulses to induce fragmentation in minerals. The development of the prototype is within the FONDEF project IDeA No. CA13I10353: “Continuous microwave pulse system prototype to assist mineral comminution”, being made by Universidad Técnica Federico Santa María. The project aims to cover the stages of design, implementation and evaluation of a high power density pulsed microwave system that allows the generation of cracks or fractures in the minerals for easy removal of the material to be extracted. Finally, it is intended that the process will generate significant savings on the energy level between the process of crushing and grinding. The equipment to develop should consider a continuous or semi-continuous mineral income to meet the characteristics of semi-industrial processing, highlighting a safe, efficient and effective application of microwaves in mineral samples to be treated, in order to induce desired fragmentation. Developmental stages considered choosing a microwave system according to the project budget, together with the design and evaluation of microwave application chamber to ensure a uniform and efficient treatment, ensuring that much of the power delivered to be absorbed by the sample. Subsequently, the development of mineral entry system continuously or semi- continuously referred to, making the prototype suitable for industrial or laboratory levels, allowing to process high volume of mineral per time. Finally, if previous results are satisfactory, it is expected to bring these advances to equipment with higher power levels, so as to generate a real impact on processing field in mining. However, to perform the above will be required more money and research resources.
