Reduction of Greenhouse Gas Pollution in Non-Ferrous Metal industry : Indian Perspective

This paper highlights the need for improving energy and materials efficiencies in the non-ferrous metal industry. The process changes taking place in the production of copper, zinc, aluminium and lead are discussed. The conventional techniques of metal extraction from ores, are being replaced by environmentally f riendly bio-hydrometallurgy/bio-reactor technology.Considerable work in this direction on laboratory scale is being done in the national laboratories and academic institutions in India. In order to achieve its full potential further research and development as well as commercialisation of bioreactor processes developed are needed.
