By Step Gold Mining Process

The entire process of gold mining can be broken down roughly into four steps prospecting, mining, extracting and refining. early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. but the search today is more systematic and precise. first, geologists know more about how gold ...

The borax method is a technique of artisanal gold mining, with its basis in the principle that borax reduces the melting point of all minerals, including precious metals like gold. the melting point of gold is 1063 c, which is a higher temperature than can be obtained by cheap torches and burners.

The miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. the miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. the wohlwill process increases purity to about 99.99 percent by electrolysis.

The gold pan is most commonly used to locate a richer paying area by sampling, so that larger production equipment can be brought into that location to work the ground to recover more gold.. there are stories in the old mining records about the ground being so rich during the 1849 gold rush that as much as 96 ounces of gold were recovered from a single pan.
