Rio Tinto cut its 2018 aluminum production target to 340-3.5 million tons. Rio Tinto announced on Tuesday that it will cut its 2018 aluminum production target by 4.2% to 3.4-3.5 million tons, influenced by the industrial operation of the Becancour smelter in Canada. The company's third-quarter quarterly report showed that the company's target is 3.5-3.7 million tons. In the third quarter, Rio Tinto's aluminum output was 880,000 tons, slightly lower than the 887,000 tons in the same period of last year and a 2.6% increase from the previous month. The company's cumulative aluminum output in the first three quarters was 2.58 million tons, down 3% year-on-year.

The company expects its Amrun bauxite development in Queensland, Australia to be completed ahead of schedule. It is expected that the first bauxite will be shipped in the fourth quarter of 2018 and will be fully operational in 2019.
