Placer mining was the most widely used method because it was affordable to a large number of prospectors. If you choose placer mining, the crusher and ball mill is common. You could get primary gold production from rock. If you want to get more pure gold production, you should choose other equipment, such as flotation cell, desorption electrolysis equipment and leaching agitation tank and carbon screen. There are equipment that used for mining in xinhaiindustry.com. You could learn more.
Silver mining, ranching
Early mining methods in the U.S. included placer mining, where miners panned for gold in riverbeds; hardrock mining, which involved extracting minerals from deep underground; and hydraulic mining, which used high-pressure water jets to extract minerals. These methods were prevalent during the California Gold Rush in the mid-19th century.
Early prospectors would use surface mining methods such as panning, placer mining, or open-pit mining to extract shallow deposits of ore. These methods involve manually removing the ore from the surface or near-surface layers of the earth without the need for extensive digging or tunneling.
