Abstract
Un proceso combinado hidrometalúrgico y de concentración para recuperar cobre y estabilizar especies contaminantes como el arsénico, antimonio y bismuto de los polvos de fundición provenientes del procesamiento pirometalúrgico del mineral sulfurado de cobre comprende una primera etapa de lixiviación en medio ácido a un rango limitado de concentración. El producto de la lixiviación se somete luego a una separación solido-liquido donde, en la solución resultante, se encuentra el cobre soluble y las especies contaminantes y, en el residuo sólido (ripios), el cobre sulfurado. Dicha solución se alimenta seguidamente a un proceso de extracción por solventes (SX) donde se genera un electrolito apto para producir diversos productos de cobre, según los intereses de los productores. El refino de la SX, que contiene dichos contaminantes se lleva a un proceso de electro-obtención con control potenciostático para estabilizar los contaminantes en forma de cátodos metálicos. El residuo sólido (ripios) de la lixiviación se somete a un proceso de concentración por flotación para obtener un concentrado de cobre apto para la venta como concentrado final o para ser devuelto como a alimentación al proceso pirometalúrgico de fundición y refinación.A combined hydrometallurgical and concentration process to recover copper and stabilize contaminating species such as arsenic, antimony and bismuth from foundry dusts from the pyrometallurgical processing of copper sulfide ore comprises a first leaching stage in an acid medium at a limited concentration range . The leaching product is then subjected to a solid-liquid separation where, in the resulting solution, there is soluble copper and contaminating species and, in the solid residue (rubbles), sulfide copper. This solution is then fed to a solvent extraction (SX) process where an electrolyte suitable for producing various copper products is generated, according to the interests of the producers. The refining of the SX, which contains these contaminants, is carried out through an electrowinning process with potentiostatic control to stabilize the contaminants in the form of metal cathodes. The solid residue (cuttings) from the leaching is subjected to a flotation concentration process to obtain a copper concentrate suitable for sale as a final concentrate or to be returned as feed to the pyrometallurgical smelting and refining process.
