Empresa Minera de Mantos Blancos S.A. operates two copper mines in Chile: Mantos Blancos and Mantoverde. Oxide ore is processed by acid leaching followed by SX-EW to produce copper cathodes. In order to define the leach process adequately for each ore, an extensive metallurgical testwork program was carried out during the feasibility study for each of these projects. A combination of heap and dump leaching was selected for Mantoverde, while a modification to the existing vat leach operation was selected for Mantos Blancos.
