The Case for a New Ni Concentrator at Widgiemooltha
In June 2007, the BHPB nickel concentrator at Kambalda reached its nameplate capacity of 1.5mtpa, only the second time it has done so (the first being in 1988/89). It has been estimated that debottlenecking of the circuit could add another 200,000tpa of ore capacity, and spending ~A$25m on the front end could increase the capacity by a further 400,000tpa to 500,000tpa, or a total of 2.1mtpa to 2.2mtpa.
