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. The gravel-like material then enters rotating drums filled with ...

Ore from the mine must be crushed before it can be refined. Powerful crusher machines reduce the ore to 1-inch (2.5 cm) pieces, increasing the ore's surface area to make the refining process more efficient. Ore is transported out of the mine and throughout the refinery via an extensive system of conveyors.
