History and heritage: Novel gold ore treatment at the Wiluna
The refractory gold ore at Wiluna has been a challenge for more than a century. A novel method of treating the most refractory ore using smelting was developed in the mid-1930s and implemented until the recovery of a more conventional method used for the majority of the ore was improved sufficiently to become more economic than smelting.
