Bauxite and Alumina Production Increase for Rio Tinto in 2015 Second Quarter
Rio Tinto recently announced its 2015 second quarter operations review. Bauxite production was 5% higher for both the second quarter and first half of 2015, setting a new record. This was primarily due to a very strong performance at Weipa and the continued ramp up of production at Gove. Gove finished the second quarter with a monthly performance equivalent to a 7.7 Mt run-rate, well on track to reach an 8 Mt run-rate by the fourth quarter of 2015.
Alumina production was up by 5% compared with the first half of 2014 (excluding production from the Gove refinery, which was curtailed in May 2014), reflecting improved productivity at Queensland Alumina and Yarwun. Rio Tinto’s expected share of production for 2015 remains unchanged at 43 Mt of bauxite and 8 Mt of alumina.
Borates production was slightly lower than in the first half of 2014, which included additional production in preparation for the commissioning of the modified direct dissolving of kernite (MDDK) plant. Titanium dioxide slag production was 18% lower than in the first half of 2014, as production continued to be optimized to align with market demand. Two out of nine furnaces are currently idled in Rio Tinto Fer et Titane (RTFT) in Quebec. In 2015, Rio Tinto’s share of production is expected to be 1.2 Mt of titanium dioxide slag (previously 1.3 Mt) and 0.5 Mt of boric oxide equivalent.
