Resumen
En Chile, la industria minera contribuye de manera importante a la economía del
pais. Sin embargo, los procesos de extracción del mineral producen toneladas de
desechos y contaminantes, lo que genera un importante gasto por el concepto de
monitoreo ambiental y gestión de residuos. Dentro de los residuos se encuentra el
cobre de baja ley, el que es mermado ya que su extracción no es económicamente
viable por métodos tradicionales. En este contexto, se hace necesaria la generación
de nuevos tratamientos para reutilizar estos desechos de modo que disminuyan su
impacto ambiental y/o incorporen valor agregado.
El refino (solución empobrecida en cobre) es uno de los desechos que presenta
un gran potencial económico como sustrato productivo de nuevas tecnologías. En
esta TESIS se plantea el uso de este desecho como sustrato para la generación de
nanopartículas (NPs) de sulfuro de cobre. Las NPs son de gran interés comercial
debido a su amplia gama de aplicaciones (biomedicina, óptica, electrónica, etc.).
Para la generación de este tipo de NPs utilizando refino este estudio se basó en la
patente titulada “Método de síntesis microbiológica de NPs semiconductoras
fluorescentes de cobre y sus aplicaciones biotecnológicas” [WO2016090508A1]. En
el presente trabajo se desarrolló un análisis técnico y económico para determinar la
factibilidad de implementar esta tecnología de producción de NPs de sulfuro de
cobre de manera sustentable en una planta piloto en el yacimiento determinado.
El análisis realizado nos permite concluir que la implementación de esta
tecnología en la línea productiva en yacimientos con determinada características es
tecnicamente y económicamente viable como sistema de tratamiento para efluentes
contaminados con cobre. Por lo cual podría ser implementada como una nueva línea
de negocios de la industria minera, lo que permitiría recuperar la inversión en un
plazo de 5 años y producir ventas anuales promedio por más de CLP$372 MM.
Estas ventas podrían aumentar proporcionalmente en base a la inversión inicial en
las instalaciones de producción.
In Chile, the mining industry contributes significantly to the country's economy. However, the ore extraction processes produce tons of waste and pollutants, which generates a significant expense for environmental monitoring and waste management. Within this waste there is low grade copper, which is depleted since its extraction is not economically viable by traditional methods. In this context, it is necessary to generate new treatments to reuse these wastes so that they reduce their environmental impact and/or incorporate added value. The refining (solution with low copper concentration) is one of the wastes that present great economic potential as a substrate for new technologies. In this Thesis, the use of this waste as a substrate for the generation of copper sulphide nanoparticles (NPs) is proposed. NPs are of great commercial interest due to their wide range of applications (biomedicine, optics, electronics, etc.). For the generation of this type of NPs synthesis technology, this study was based on the patent entitled "Method of microbiological synthesis of semiconductor fluorescent copper NPs and their biotechnological applications" [WO2016090508A1]. In the present work, a technical and economic analysis was developed to determine the feasibility of implementing this technology for the production of copper sulphide NPs in a sustainable manner in a pilot plant. These results allows us to conclude that the implementation of this technology in the production line of the deposit is technically and economically viable as a treatment system for copper-contaminated effluents. It could be implemented as a new of the mining industry business line, which would allow the investment to be recovered within 5 years with average annual sales of more than CLP $ 372 MM. These sales could increase proportionally based on the initial investment in the production facilities.
