Mining corporation Rio Tinto has reported a strong quarterly production performance and a wave of productivity improvements. Only mined copper production was lower, guidance has been revised.

Pilbara iron ore shipments were 85.8 mill. t in the third quarter (100 % basis), assiste[ds_preview]d by improved rail capacity and performance. This was 6 % higher than the third quarter of 2016, which was impacted by shiploader maintenance. Quarterly bauxite production was 12.9 mill. t for a second consecutive quarter, 4 % more than the third quarter of 2016, driven by strong performances at Gove and Weipa. Third party shipments for the third quarter were 8.2 mill. t. Bauxite production guidance is revised to between 50 and 51 mill. t (previously 48 to 50 mill. t).

Mined copper production was 3 % lower than the corresponding quarter of 2016 due to lower copper head grades at Rio Tinto Kennecott and Oyu Tolgoi. Mined copper guidance is revised to between 460,000 and 480,000 t (previously 500,000 to 550,000 t) following the third quarter impact of the delayed ramp-up of the Escondida expansion, and fourth quarter mine sequencing changes at Rio Tinto Kennecott. Titanium dioxide slag production increased by 23 % compared to the third quarter of 2016, reflecting higher market demand.
