Rio Tinto partners with Indian firm to explore low-carbon aluminium project
The potential development could see up to 1 million tonnes per annum (mtpa) of primary aluminium smelting and 2 mtpa of alumina production, both energized by renewable wind and solar power, supported by pumped hydro storage, the global miner said. The initial phase of the project would involve studying the possibility of a 500,000 tonnes per annum primary aluminium smelter at a "favourable" location in India, it added.
