SMELTING: A metallurgical process that transforms the raw material, copper concentrate (which is 25-30% copper), into metallic copper approximately 99.7% pure. REFINING: An electrochemical process yielding high-purity (99.99%) copper. ACID PLANTS: Chemical process transforming the SO2 from smelting gases into sulfuric acid. OTHER PROCESSES: Different processes to recover other components of copper concentrate, such as precious metals, tellurium and nickel. Meanwhile, other processes are implemented to recover the heat given off in smelting and use it to generate electricity, thus optimizing the energy efficiency of all the processes as a whole.
