Abstract
El potencial energético solar de la zona norte del país es uno de los más importantes a nivel mundial, el aprovechamiento de este recurso como fuente de energía para las operaciones mineras de esta zona de Chile, haciéndolas más sustentables, se ha tornado en los últimos años un desafío técnico económico para las compañías mineras con más renombre en el país. La tecnología termosolar ha presentado un camino atractivo para cubrir la demanda del recurso térmico en procesos mineros, intensivos en consumo de combustibles fósil como aporte de calor convencional, estas tecnologías ya aplicadas en proyectos que se encuentran actualmente en operación en faenas mineras especialmente para procesos de SX y EW nos entregan mediante la investigación de la presente tesina conceptos importantes a tener en cuenta ante la evaluación de una inversión para este tipo de proyectos, sus ventajas ambientales y de cuidado con la comunidad como también sus limitantes técnicas que también pueden involucrar las características geofísicas de la zona norte del país, pudiesen llegar a afectar el VAN de este tipo de proyectos., toda esta información y datos recopilados permitirán establecer mediante un análisis criterios a considerar para el desarrollo de esta tecnología en el mundo de la minería. Finalmente se presentara un caso de evaluación correspondiente al reemplazo del aporte de calor (energía térmica) convencional por el desarrollo de un proyecto termosolar para el proceso de electrorefinación del cobre, de este caso se obtendrán los aspectos más importantes que influyen en la rentabilidad del proyecto y se aplicara modelación estocástica para evaluar en qué medida afectan en VAN del proyecto principalmente el precio de los combustibles y la inversión del proyecto y el volumen de combustible desplazado.
The solar energy potential of the northern part of the country is one of the most important worldwide, the use of this resource as a source of energy for mining operations in this part of Chile, making them more sustainable, it has become in recent years an economic technical challenge for mining companies most renowned in the country.Solar thermal technology has presented an attractive way to meet the demand of the thermal resource in mining, intensive processes consumption of fossil fuels as a contribution conventional heat, these technologies already implemented on projects that are currently in operation in mining especially for processes SX and EW deliver us by researching this thesis important concepts to consider before evaluating an investment in such projects, its environmental benefits and care with the community as well as their technical limitations which may also involve the characteristics geophysics in the northern part of the country, they could eventually affect the profitability of such projects., all this information and data collected by analyzing possible to establish criteria to be considered for the development of this technology in the world of mining.Finally, a case for the replacement of the supply of heat (thermal energy) standard for the development of a solar thermal project for the process of electrorefining of copper, this case evaluation will present the most important aspects that influence the profitability of the project will be obtained and stochastic modeling were applied to assess the extent to which the project VAN affect mainly the price of fuel and the project investment and the volume of fuel displaced.
