In Australia, the two preeminent options for refractory gold ore pretreatment are roasting and biooxidation and this development is reported. The trial of pressure cyanidation of stibnite concentrates at the Golden Spec mine in Australia is described. Pyrolysis, the Nitrox/Redox process, the Artech/Cashman process and the Caro's acid process have not gained commercial status so far.
Initially working with singlejack bits and black powder, they produced the goldrich ore that was processed onsite. Larger machinery was later skidded up and down mountainsides and rock faces with a steam donkey to reach the mine. Over its lifetime, a hydropower plant and sawmill, along with a stamp mill and various oreprocessing machinery, were installed and abandoned. Calamities such as ...
