Abstract: In view of the current environmental situations of copper smelting enterprises in which copper concentrate was used as the raw material and according to the procedures and methods of locale environmental supervision, the technical points of locale environmental supervision in such processes as preparation area, melting area，electrolysis area and acid area were put forward. It was suggested that the situations of emissions of heavy metal, SO₂ and smoke-dust in compliance with the emission standards, the safe disposal of the dangerous solid wastes and the availability of emergency response programs and measures of environmental risks should be especially supervised. The technical points could offer technical guidance for the environmental supervision.
