Gold mining consists of the processes and techniques employed in the removal of gold from the ground," he noted. Gold extraction ... This is a mercurybased process which works because of gold's willingness to be dissolved by mercury. The mercury is applied on an ore, picks up the gold, and the resulting amalgam is distilled, with the ...

next ›. There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river ...

More than 90 percent of the world's gold has been produced following the rushes of the mid to late 1800s [source: World Gold Council ]. 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 placer mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging. Using gravity and water to separate the dense gold from the other materials that surround it, this is the most common gold mining category for amateur gold hunters. Hard rock mining is the process of using open pit or underground mining tunnels ...

The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it's mined with openpit mining techniques.
