Mining methods for gold are similar to other metals. Gold is so valued that the discovery of a new place to mine has sometimes caused a gold rush. Often, gold is found as a native element. This means it is not part of an ore, and does not need extracting. Most of the gold on Earth is deep inside the Earth's core because it is dense.

Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
By-product gold mining. Gold is also produced by mining in which it is not the principal product. Large copper mines, such as the Bingham Canyon mine in Utah, often recover considerable amounts of gold and other metals along with copper. Some sand and gravel pits, such as those around Denver, Colorado, may recover small amounts of gold in their ...
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.

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 final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or ...
