Project Details


The project entails the expansion of copper mine El Abra, with the aim of tripling the current production. It also considers exploiting the primary resources of the mineral or sulfide, which implies changing the current production of cathodes to concentrates, requiring the construction of a concentrator plant and the increase of the water supply, for which it is necessary to desalinate seawater.
