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.
