The company had planned to build a 0.36Mt aluminium smelter alongside a 1Mt alumina refinery, but is now planning a 0.72Mt smelter in direct competition with rival Vedanta Aluminium.

Vedanta operates a 0.5Mt smelter and a 1Mt alumina refinery in the region.

Hindalco’s strategy is to dominate the primary aluminium industry through its Indian operations.
