Abstract

Un procedimiento para la extracción de cobre, a partir demena o concentrado de cobre sulfúrico el cual comprende las siguientes etapas: Someter la mena o concentrado a oxidación con presión en presencia de oxígeno y una solución ácida conteniendo iones de haluro y sulfato, para obtener una suspensión final de oxidación con presión, sometiendo la suspensión a una etapa de separación líquido/sólido para obtener un filtrado de oxidación con presión y un residuo sólido conteniendo una sal básica de sulfato de cobre insoluble; Lixiviar la sal básica de sulfato de cobre producida mediante la oxidación con presión en una segunda lixiviación con una solución ácida de sulfato para disolver la sal básica de cobre para producir un licor de lixiviación conteniendo sulfato de cobre en solución y un residuo sólido final; separar el licor de lixiviación del-residuo sólido; someter el licor de lixiviación a un procedimiento de extracción con disolvente para producir una solución concentrada de cobre y un refinado con cobre empobrecido y reciclar por lo menos una porción del refinado a la oxidación con presión.
