Abstract

La invención de la presente solicitud divulga un proceso para la lixiviación de minerales de cobre que permite una recuperación más rápida y con mayor rendimiento denominado SHL (Solar Heap Leaching/Lixiviación solar en pilas de minerales), donde: a.- la pila de minerales se riega con soluciones de lixiviación calientes;b.- la pila está cubierta para evitar evaporación de agua y pérdida de calor y al mismo tiempo permitir la entrada de radiación solar y calentarla; c- las soluciones de lixiviación efluentes de la pila se someten a extracción con solventes o precipitación química para recuperar el cobre; d.- Las soluciones pobres en cobre resultantes del proceso de recuperación de cobre anterior se calientan mediante intercambio de calor con un fluido térmico caliente; e.- el fluido térmico se calienta mediante radiación solar;.f. las soluciones pobres en cobre calientes se acumulan para ser alimentadas a las pilas de manera continua incluso durante las 24 horas del día. El proceso divulgado se realiza en un sistema en el cual se cuenta con un colector solar de diseño original con seguimiento solar basado en concentración de la radiación solar mediante lentes Fresnel.
