Placer mining, hard rock mining, byproduct mining and by processing gold ore. Each of these categories has it's own unique methods of extracting the gold from the surrounding materials. In placer mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging.Early Gold Mining Methods Sierra Foothill Magazine,Miners from Sonoran Mexico had a technique for pulverizing gold ore that required no water for the initial stages of gold processing. Called the arrastre, this system consisted of an upright axle with large spokes. Horses or mules, hooked to the outside edges of the spokes, pulled them around and around.
Summary. Historically, the majority of gold was mined from "placer deposits", where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcrops.Some early miners also used an early form of hardrock mining, digging solid veins of gold Methods of mining Te Ara Encyclopedia of New Zealand,Gold mining was rough, physical work. Where alluvial gold was very rich, it could be obtained with a shovel and pan. However, pans were used mainly for prospecting. Simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth the heavier gold Early Gold Mining Methods Sierra Foothill Magazine,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. Children view a small long tom at a Gold

Other surface techniques include quarrying and strip mining.Gold Mining Methods groundtruthtrekking,Placer Mining. The stereotypical grizzled gold-rush prospector panning for gold was searching for "placer gold", or gold deposited in a waterway. Placer mining takes a variety of forms, including panning, "sluice-boxing", hydraulic mining, and dredging. All of these techniques use gravity and water to separate the dense gold

Different types of matting can work better or worse depending on the size of gold you typically find, so experiment with what works best in your area. Conclusion Every gold prospector should be conscious of the amount of gold that is being lost from their sluicing operation.RECOVER MORE GOLD WITH MY GOLD PANNING TOOLS GOLD MINING,Gold is the most malleable and ductile of all known metals. One ounce of gold can be worked into a sheet measuring five meters flat. Gold can be flattened as thin as .000127 millimeters or about 400 times thinner than a human hair. Pure gold is soft and usually mixed with other metals like: silver copper platinum and palladium(PDF) Mining Methods: Part I-Surface mining,Solution mining includes both borehole mining, such as the methods used to extrac t sodium chloride or sulfur,and leaching, either through drillholes or in dumps or heap s on the surface. 2
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces.
