| Resumen en portugués | Chuquicamata´s environmental regulation is based on two governemt decrees of the Ministry of Mining: number 185, Sep 1991 wich regulates the operation of SO2 dust and As emissions along all the Chilean Republic; No. 132 ( Jun 1993) wich states the decontamination Plan of the Chuquicamata Division of CODELCO-Chile. Before the decontamination plans, 55 % of the Sulphur and 25 % of the Arsenic contained in the smelled concentrations were emited to atmosphere. Smelting process was based on the operation of a flash furnace, a Teniente converter and two reverb furnaces. By the end of 1995, 30 % of the sulphur and 15% of the arsenic contained in concentrates were emitted. This was attained by replacing the two reverbs by a second Teniente Converter, and the enlargement of the acid plant capacity, wich has allowed capture of 100 % of smelting gases and a fraction of the Peirce-Smith converting gases.All of this has substantially increased the sulphuric acid production, and has improved the metallurgical indicators of management and quality of life in the Chuquicamata smelter |
