Indian mines minister, Mr B Handique said consumption would also reach 5Mt by 2015 and 10Mt by 2020 on rising demand from sectors such as infrastructure, construction and transportation.

The Indian aluminium industry produces about 1.3Mt compared with the world output of 40Mt, Mr Handique said.

Stating that exploitation of aluminium resources has to be guided by long-term national goals and perspectives, Mr Handique said it was necessary to explore new bauxite deposits and develop technologies for using low-grade bauxite to meet the growing demand.
