On November 29, Rio Tinto announced that it would suspend production of alumina at its Gove refinery. It was hardly a surprise; the smelting plant was reputed to be losing Rio Tinto $20 million to $30 million per month and closure was based on the company’s commercial accountability to its shareholders. It had become increasingly clear that even with access to cheap gas to offset the burden of dependence on heavy fuel oil the Gove operation was commercially unsustainable.
