BHP Billiton’s alumina production at its Worsley plant in Western Australia was up almost 8% over the previous quarter, the company announced in its June production report.
The Worsley plant produced 747,000 tonnes of alumina for the June quarter, compared to 688,000 in March.
Despite the increase at Worsley, BHP’s worldwide alumina production was down 9% when compared to the same time last year.
Sales at Worsley rose from $683,000 tonnes per annum in the March quarter to $731,000 in June.
BHP also reported its Worsley expansion project is 75% complete and is expected to start production in the first half of 2011.
The $2.5 billion expansion will increase production at the mine by more than one million tonnes per annum, the company said.
