CLC is a mining company with the biggest open pit mine of copper in Europe and a hydrometallurgy plant for mineral beneficiation considered unique around the world. It produces 72,000 tons per year of electrolytic copper, grade A through an integrated secondary copper atmospheric leaching plant.
The CLC Hydrometallurgical Plant is very innovative and one of the most technologically advanced in the world for treating copper through the concept “Mine to Metal”. The use of optimized applied process technology maximizes the reutilization of water, energy and material resources. CLC uses a sustainable “Clean Technology”, avoiding the generation of acid gas typical from conventional copper smelters; liquid effluents are perfectly controlled to meet the most stringent regulations, and process tailings are disposed in dry conditions, and a tailings pond is not needed.
