The ethics of environmental protection is based on the moral responsibility of a man not to endanger his living environment because it is the only way for creating the conditions for a better life quality. Environmental consciousness (EC) is characterized by a high awareness about the environment, especially in urban areas with mining-metallurgical sources of pollution. Raising EC in such environments causes acceptance and ecological and social responsibility. A mining-metallurgical complex plant represents an important source of pollution of urban areas. In that sense, Bor is an interesting urban area having in mind that it represents one of the most important ore and metal production centers in South-East Europe. What defines the EC of Bor inhabitants is derived from the very town and its economy. The research encompasses concrete environmental problems of the mining town Bor and its surroundings. The components of the EC of people living in Bor were analyzed according to the awareness, knowledge and attitude method, having in mind the extent to which the environment has been polluted in this area. It has been concluded that the perception of people living in Bor about the state of the environment depends on numerous factors -first, whether the employee works for the RTB Bor Company or not.Palabras clave: conciencia ciudadana, producción de cobre, problemas ambientales, minería RTB, fundidora Bor RESUMEN La ética de la protección ambiental se basa en la responsabilidad moral de una persona de no poner en riesgo el ambiente que habita porque es la única manera de crear condiciones para una mejor calidad de vida. La conciencia ambiental (CA) se caracteriza por el cuidado del ambiente, especialmente en zonas urbanas donde existen fuentes minero-metalúrgicas de contaminación.
