Mining giant Rio Tinto has appointed the former boss of tollroad owner Transurban, Chris Lynch, as its new chief financial officer.
Mr Lynch will replace Guy Elliot on April 18.
Rio said Mr Lynch will remain on the board and become an executive director and member of the executive committee as chief financial officer-elect on March 1.
The appointment comes a month after Rio Tinto boss Tom Albanese stepped down after the global miner announced a multi-billion dollar writedown of its aluminium and coal assets.
Rio Tinto recently announced a full year net loss for 2012 of almost $US3 billion ($A2.91 billion) and was criticised for its near total dependence on iron ore despite calling itself a diversified resources company.
