Over the border in Queensland, mush of the opal mining activity centres around opencut mining, whereby overburden (the top soil) is stripped away to reveal the layer/s of ironstone of which the boulders are removed for processing. From there, the rough opal is sent off for either processing and then sold, or sold in its rough form.
Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
