Confirming the presence of gold beneath a particular area with the help of a metal detector is not only easier but can also be carried.

The Mechanization of Gold Mining Gold mining must have been the most lucrative business of all times. The most critical and the very first step in gold mining is locating the presence of gold in a particular area. Gold panning is not commercially suitable for sorting out gold. It may be present in the form of particles in loose sediment in places called placer mines; or in the form of ores in hard rocks, buried deep down in the earth.

It can be done manually by a process called gold panning, or with the help of a metal detector. Different techniques are used in extracting gold from placer mines and hard rocks. In the former case, gold is recovered with gravity separation method; and in the latter, chemical reactions separate the gold from other metals and substances.

Gold mining is the term used for the integrated processes and techniques employed in finding and extracting gold from streams and earth.
