Whether it's commercially extracting a rare ore from the ground or sweeping black ooze by hand for recreational purposes, everyone loves to see the glittering gold from flour or even a gold nugget. There are many ways to extract the precious treasure from the earth. Hand panning is a method used for prospecting and recreational hunting for gold. Gold panning is a technique used to separate fine materials from gold using water and a special technique. A commercial mining operation may use a gold pan to prospect an area before bringing in larger, more expensive mining equipment. Using a gold pan is one of the oldest and simplest forms of gold mining. (Colledge) The most important thing to remember about gold panning is that while it can be relatively effective at capturing gold, its main disadvantage is that it can only process a limited amount of material to the time. This is why gold panning is not used as a tool of commercial mining in the name of processing large quantities of materials for a fee. A pan of gold can be used to access places only accessible on foot. But the material must be rich enough to make the time spent worth it if there is only a limited amount of material to process. The primary use of a gold pan other than recreational purposes is to locate an area with gold-bearing soil so that later, commercial mining equipment can be brought in to recover gold from a large area of ​​soil . The 1948 image of a miner crouching beside a river, reaching into the water with a pan is a symbolic image of the California Gold Rush. This is the tool used by the first miners of the gold rush. Although the first person to make his fortune from gold mining was not a gold prospector himself, but was a salesman called o......middle of paper......sing the rocker is that it cannot trap the very small particles of gold known as mealy gold. Although miners found a way to trap the gold from the flour in the seesaw using mercury at the bottom of the seesaw. Gold is trapped in mercury due to the chemical composition that mercury contains. The miners then heated the mercury and gold concentrate, as only the vaporized gold residue remained. (College) A long tom uses the same theory as the cradle but the long tom. Instead of pouring water into the box like cradle, the long male used a wooden paddle wheel to maintain the desired water flow for the miner. The gravel was then shoveled into the wooden box and the water carried it into the sometimes 100 foot long box over a set of riffles to catch the gold bearing material. The material was then fully processed to collect only the gold mineral.
