Abstract

The current treatment of copper ores containing atacamite and secondary copper sulphides consists of heap leaching, by the TL process. Copper recoveries by this treatment are very low (less than 50 % for operating times higher than six months). In order to improve the copper extraction yields, several treatment options are presented in this work, wich consist on promoting the acid leaching of the atacamite and the indirect bioleaching (BRISA process) of the secondary copper sulphides. All the options lead to improved copper recoveries in comparison with the current treatment. An economic estimation of each option of treatment is included, with really attractive results.
