Aug 19 (Reuters) - Rio Tinto (LON:RIO) RIO.AX on Wednesday cut its refined copper outlook for fiscal 2020, citing a delay in restarting a smelter in its mine in the U.S. state of Utah.
The miner said it now expects full-year refined copper production between 135,000 tonnes and 175,000 tonnes, lower than its previous range of 165,000 tonnes to 205,000 tonnes.
