Codelco to invest US$ 371 million to reduce arsenic in Chilean copper

On 31 October 2016, Chilean state owned copper mining company (Codelco) announced a US$ 371 million investment on a processing plant to reduce the levels of arsenic detected in its copper. The project will be led by Codelco's sister company, EcoMetales, and entails the building of a processing facility in Calama (Northern Chile) by 2020, with the capacity to process up to 200k tons of copper per year. Given the size of the required investment, EcoMetales is considering incorporating partners to help finance the project (La Tercera). The level of arsenic present in Chilean copper has become a significant problem for the industry, given the increasingly stricter environmental requirements for transport and processing on a global level (Tele13).
