How is gold mined?

In placer mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging. Using gravity and water to separate the dense gold from the other materials that surround it, this is the most common gold mining category for amateur gold hunters. Hard rock mining is the process of using open pit or underground mining
