Placer miningis the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Panning Gold panning is mostly a manual technique of separating gold from other materials.
Gold pans: Most people immediately think of the gold pan as the most important tool for gold prospecting. However, a brain isrequired to operateit,select the right location on the stream,get permission to enter the land and decide that the land has potential. Without a well-prepared brain, the gold pan will not find very much.
There are four main mining methods:underground,open surface (pit),placer, andin-situ 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 channels, beach sands, or other environments.
Modern gold extraction techniques such as “heap leaching” is a new method of treating low grade gold ore by piling it into an outdoor heap, then sprinkling cyanide solution over it. Within a few weeks, the cyanide will have dissolved the gold and it runs down a sloping, impermeable pad into large sluices.

Chemical Leaching. Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost.

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The largeminingcompanies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their ...
