Gold mining consist of a number of processes and techniques, employed to extract raw gold from earth. These gold extraction techniques include gold panning, metal detecting, sluicing, dredging etc.
This metal is an expensive element; thus, individuals and nations have always been interested in gold extraction, mainly to gain economic benefits. In the United States of America, a major rush of gold mining took place with the discovery of gold at the Reed farm in North Carolina, in 1799. Thirty years latter, this metal was discovered at the southern Appalachians in Georgia, which was followed by the California Gold Rush in 1848-52 in the Sierra Nevada, as a result of which a lot of people started to settle down in California. This was only the beginning of the history of this metal discovery and mining in America. Later on, many states in America, like Alaska, Alabama, Texas, Virginia and many more, were found to be blessed with reservoirs of this metal.
