Process To Mill Gold

An excavator removes any residual steel or explosives before it is fed into the mill for processing. Processing. Gold at Macraes is known as ‘refractory ore’, which means it is ultra-fine and resistant to the typical cyanide leach process, typical of most gold processing plants.

  • Extracting Gold | HowStuffWorks Extracting Gold | HowStuffWorks

    Removing the gold-bearing 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.
