Rival miners have cautioned over a weaker outlook and Rio Tinto Group last month reported a decline in first-half profits and halved its dividend.

The daily Argus ICX 62pc iron ore index was at $108.75/dry metric tonne on 10 August, lower by 33pc from a year earlier.

The firm will invest 575bn rupees [$7.23bn] in the two projects that have received high-level clearance approval from the Odisha government.

China is a large consumer of iron ore.

Rio Tinto is not concerned about China's plans to centralise iron-ore purchases and has strong ties with its customers, the Australia CEO for the global miner said on Friday.

In April 2020, BHP agreed to a 100 million yuan ($14.6 million) sale with Chinese steel giant Baosteel and pledged to continue sales in yuan.
