SYDNEY (Reuters) - BHP Billiton Ltd , the world's biggest miner, has agreed to sell its Yabulu nickel refinery to Australian mining magnate Clive Palmer for an undisclosed amount, BHP said in a statement on Friday.
BHP would write down the value of Yabulu assets by $500 million (306 million pound) and write off a further $175 million in unrecoverable tax benefits. The sale is expected to be finalised by July 31.
The Yabulu refinery is in northern Australia.
