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 tunnels to retrieve the gold from the rock.
Removing the goldbearing 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.

This process is continued until only heavy "black sands" (such as ilmenite, magnetite, and pyrite) and gold remain. The material is dried and the gold removed (perhaps after using a magnet to remove some of the black sand). Panning is slow, backbreaking work, but in experienced hands there is little or no loss of gold. See also placer mining.
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. Insitu mining ...
