Transforming resources into reserves is a key elementElements that will help miningMining companies to meet the expected copper demandCopper demand to transform modern societies. In this sense, Codelco ChileChile has been working in the development and implementation of a chlorideChloride leachingLeaching process to increase the production of copperCopper unit in its northern district in the region of Calama, ChileChile. This paper describes the efforts done in this area with particular focus on the designDesign, constructionConstruction, and commissioning of a chlorideChloride leachingLeaching demonstration plant at Radomiro Tomic Division.
