Incorporated in Canada in 1906, Cominco Ltd. has emerged as a leading integrated zinc and copper producer. With mines in Canada, the United States, Chile, and Peru, Cominco is the world's largest producer of zinc concentrate as well as the fourth-largest zinc metal refiner. Additionally, Cominco produces lead, silver, gold, germanium, and indium.
The CESL process [56, 65] is based on chloride-accelerated oxidation pressure leaching with the control of the amount of the acid to ensure that copper is transferred to the basic cupric sulphate salts, iron to haematite and sulphur to the elemental form, which is similar to the leaching process developed by Noranda in the 70s. After separating ...
