The model led to major changes in the ways Bagdad personnel analyze and extract copper. It integrates data from sensors around each project to examine new tactics that enhance the performance of processing mills, crushers and the mine itself. Previously, Bagdad staff estimated all the ore entering the mill was the same type.
El Soldado. El Soldado is a copper mine located in the Cordillera de El Melón, commune of Nogales, Valparaíso Region, 125 kilometers north of Santiago; in an area where productive activities such as mining, agribusiness, small peasant family farming and tourism coexist.
