The antiseptic properties of copper have been known for years. Its particles can purify water and eliminate infections. And Chile, the world’s largest producer of the metal, is leading the development of new products that take advantage of copper’s disinfecting qualities.
An significant part of these efforts are undertaken in the state-owned mining company Codelco, which seeks to increase its sales and reach new markets by reinforcing the new uses for copper. The company’s latest innovations include cages made of this material for fish farming, especially for the production of salmon.
The cages were tested in cultivation centers in southern Chile and caused a considerable reduction in the diseases affecting the fish. The product will now be presented as part of what the state owned company offers at the Chile pavilion in the 2010 Expo Shanghai, which will take place next May, as Codelco Executive President José Pablo Arellano commented.
At the Expo in China Chile will also promote copper’s antibacterial properties, which have been applied with great success in the hospital of the northern city of Calama.
