Gold mining is the process of mining of gold or gold ores from the ground. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to identify placer gold deposits to be evaluated for commercial viability.
Smallscale gold mining operations in developing countries are major sources of toxic mercury pollution, using techniques that haven''t changed much since the California Gold Rush 150 years ago.

The 1849 California gold rush brought gold seekers from American and many countries to the San Francisco area. Excitement combined with new international tools and methods made the rush
The New State. People used different methods for gold mining. A cradle was one. Water was poured into it and rocked to separate heavier gold from the soil. A Long Tom was longer version of it. In another method, water and soil were sent through long ramps called sluices. Some miners panned for gold.
This mining method worked by getting a hose with pressurized water and blasting it at a hill. Because gold came from the top of the Sierra Nevada mountains some of the gold would be on hills. So by shooting this water at a hill the gold would roll down the hill and then the miners would just pick up these big gold nuggets.
Panning. Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material.
Much like the Mother Lode Region, there are thousands of areas to explore that have produced gold in the past. Many areas were mined using hydraulic methods, as well as hand placering and hard rock mining. The richness of this goldfield extends north into Southwest Oregon, where much gold has also been discovered.
Water was essential to be successful in finding gold and separating it from the residue of dirt and gravel. Because water wasnt always nearby or available, miners created flumes, or long wooden chutes, that brought water down to the digging site. A sluice box did most of the work for the miners.
Mexican miners used the horsedrawn arrastre to crush goldbearing 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. Children view a small long tom at a Gold Rush reenactment along the South Fork of the American River, Coloma, California.
#0183;#32;The California gold rush started with the discovery of small pieces of gold in the Sacramento Valley. News began to spread after this discovery, which led thousands of prospectors to flood into the area around San Francisco. Between 1848 and 1849, the nonnative population in California swelled from around 1,000 to 100,000. About 2 billion worth of gold and other precious
#0183;#32;During the California Gold Rush, there were many ways to mine for the gold. The first was to simply pan for it. This is the oldest and simplest way to mine for gold. This method was to remove the gold from the surrounding rock around it. This simple method consisted of placing some material with
How Did They Get The Gold Out? Placering: When the Gold Rush began, few of the people in California knew anything of the methods used to procure gold from the quartz veins and river gravels. Because of the richness of the river gravels in the earliest days, panning was an early method of choice, but it was inefficient, backbreaking labor.
