PERTH, AUSTRALIA--November 11, 2013--Researched by Industrial Info Resources Australia (Perth, Australia)--The future of Rio Tinto Limited's (NYSE:RIO) (Melbourne, Australia) Gove alumina refinery is still far from certain, as all concerned parties continue negotiations to secure a supply of natural gas for the facility. The refinery and bauxite mine on the Gove Peninsula, 650 kilometres (400 miles) east of Darwin, has lost more than $190 million per year in recent times, largely due to the high cost of operating diesel generators to power the energy-intensive refinery.
