Mining Classifiers, Sifters, Pans | High Plains Prospectors

It is very important to try to filter out any unnecessary material prior to using your gold processing equipment of choice to recover gold. This is due to something called specific gravity. Which essentially means that a larger piece of material, sometimes called overburden, say a piece of granite, will weigh less than a smaller piece of gold.

Gold: History of Use, Mining, Prospecting, Assay & Production

Early Gold Finds and Production. Gold was produced in the southern Appalachian region as early as 1792 and perhaps as early as 1775 in southern California. The discovery of gold at Sutter's Mill in California sparked the gold rush of 1849-50, and hundreds of mining camps sprang to life as new deposits were discovered.

Tailings - Wikipedia

In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which ...

Extracting Gold | HowStuffWorks

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 steel balls.
