    To isolate pure gold, mining companies use a complex extraction process. The first step in this process isbreaking 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 steel balls
