Figures released by the Strategic Resource Institute show that Rio Tinto Alcan has increased production of bauxite, alumina and aluminium for Q2 2013 when compared to the same period last year.
Bauxite production was up by 21%, alumina production up by 15% and aluminium production also up by 15%.
The global mining giant expects its share of bauxite, alumina and aluminium production in 2013 to be 34Mt, 7.3Mt and 2.5Mt respectively.
In terms of its H1 2013 performance, the company has recorded a 16% increase in bauxite when compared with H1 2012, a 7% increase in alumina and a 14% increase in aluminium.
Pacific Aluminium figures, on the other hand, paint a gloomy picture with bauxite production in Q2 2013 down 4% on the same period in 2012, alumina production down 30% and aluminium production down 5%.
Where half year figures are concerned, Pacific Aluminium's bauxite output remained static while alumina production was down 20% and aluminium down 6%.
Rio Tinto Alcan attributes its success to strong operational performance driving higher volumes at its Weipa bauxite mining facility, increased capacity at its Yarwun aluminina refinery in Gladstone and improved third party demand.
