Placer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

Centrifuges operate in cycles that can be preprogrammed or determined manually depending on the equipment and the material processed. After a cycle is completed, the miner can then extract gold from the ridges of the centrifuge vessel. For small scale centrifuges, cycles usually last around hours. Operating a centrifuge takes skill as it must be tuned to the material it is processing

Creation of a Placer Gold Deposit Here is an example. Through geologic processes millions and millions of years ago, a gold vein forms in some type of rock. This vein is 10,000 feet up on a mountain and 20 feet under the ground. As time goes by natural erosion takes place. The rock over the vein is slowly eroding away, and after years it slowly crumbles away. Now we have an exposed vein of
