Gold Rush: 1848–1860: Mining Techniques | Picture This
A study of the mining techniques used during the California Gold Rush reveals more than just information of how to extract gold from the earth. The various types of mining techniques also show the cultural melting pot that was then and is now California and they reveal the myth behind the history of the Gold Rush.

Above and below: the rocker or cradle was a simple way of straining gold from lighter rock. Mexican miners used the horse-drawn arrastre to crush gold-bearing rock. Left and below: Stamp mills were a more sophisticated technique for crushing gold ore. Huge nozzles such as these were used for hydraulic mining.

Methods of Gold Mining - geologyin.com
Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes open-pit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest open-pit gold mines in North America located on its Goldstrike mine property in northeastern Nevada. Other gold mines use underground mining, where the ore is extracted through tunnels or shafts.
What Tools Do Miners Use to Find Gold? - Reference.com
Apr 01, 2020 · Gold prospectors use tools such as gold pans, sluice boxes, drywashers or highbankers to find gold. Modern prospectors may use metal detectors to help locate likely spots, while commercial mining operations use trommels to help crush rocks and separate gold.
Gold panning - Wikipedia
Gold panning, or simply panning, is a form of placer mining and traditional mining that extracts gold from a placer deposit using a pan. The process is one of the simplest ways to extract gold, and is popular with geology enthusiasts especially because of its low cost and relative simplicity. The first recorded instances of placer mining are from ancient Rome, where gold and other precious metals were extracted from streams and mountainsides using sluices and panning. However, the productivity r

Panning is used to find alluvial gold. Alluvial gold is specks or flakes of gold the is found in creek bed, shallow streams, and in shallow dirt. To pan, a miner would take small amount of soil or gravel that is thought to contain gold, the miner would also add a significant amount of water into a steel pan, then the miner would move the pan in a swirling motion, this motion would then 'swirl' out the mud and water leaving the gold behind.
Extracting Gold | HowStuffWorks
Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.
What methods did the miners in the gold rush use to find gold ...
Diggers in the gold rush used the following equipment and methods to find gold:Panning involved the use of a solid pan. An amount of potentially gold-bearing dirt was placed in the pan with some ...
Gold Panning -History of a Prospecting Method (Tool)
Gold panning is the cheapest method/tool (and oldest method of mining gold) of placer mining to extract gold from gold placer deposits which occur in river/stream beds. Evidence of gold panning and other placer mining methods reach way back to the times of the Romans. Early the history of metals, the Spanish used placer methods, including panning during their conquest of South America in the ...
What Were Some of the Tools That Were Used in the Gold Mines ...
Sep 29, 2017 · The Gold Rush of the 1840s ended the era of the solitary miner sitting by a stream with pan in hand. Throngs traveled to California hoping to find their fortunes. Tools were soon developed to easily extract gold from rocks and riverbeds. Many of these tools have been found in the original mines above and below ground.
Gold Mining Methods - groundtruthtrekking.org
In addition, many small mines use mercury for the separation of gold, while large mines instead use cyanide. Both chemicals are very toxic, and mercury is persistent in the marine food chain. Gold mining in Alaska. Gold mining has a long history in Alaska, beginning with the Klondike Gold Rush at the end of the 1800s. Even today there exist a ...
» gold mining history
Each mining area also has distinctive sizes and shapes of gold particles. Some areas are noted for the size of the nuggets produced; other areas produce only microscopic particles of gold. The type of gold in the area determines the method of searching for it. All placer gold originated in a lode vein.
Mining Techniques of the Sierra Nevada and Gold Country
Hydraulic mining was a variation on ground sluicing where the water delivered to the site would be shot through a nozzle at high pressure onto the face of the cliff, thereby washing away tons of boulders, gravel, dirt, and gold. The first use of this method is credited to Edward Mattison in 1853.
Mining History and Geology of the California Gold Rush
It is difficult to assess the total production of these placering methods, but in the period of the Gold Rush itself (roughly 1848-1853), perhaps 10-12 million ounces of gold were produced (worth many billions of dollars at today's prices). This was the era when the individual could hope to strike it rich, and quite a few lucky miners did.

Prospecting methods | Ergo
The simplest way to find gold was to use a tin dish at the side of a stream. The best spots were gentle bends where gold had been trapped rather than travelling on with the course of the stream. With patience and a gentle rocking motion, miners successfully separated the bright gold from the dull clay of Victorian rivers.
Panning methods during the California Gold Rush | Britannica
[Music in] NARRATOR: A few men did get rich. But most of the miners--still poor and a few years older--would have to make a fresh start. They'd farm or take jobs . . . marry and raise families. The gold adventure that brought over 200 thousand people to California had ended--but the high hopes and raw energy remained.
Researching Evidence of Past Mining to Locate Gold Deposits
One of the best ways to find an area to prospect for gold is to locate areas that the old-timers have already mined. Miners have been actively searching for gold in most of the U.S. for well over 150 years now, and there are likely very few areas that are undiscovered.
