Gold
mining.
Gold mining consists
of the processes and techniques employed in the removal
of gold from the ground. There are several techniques
by which gold may be extracted from the Earth.
Gold panning is a mostly manual technique of sorting gold.
Wide, shallow pans are filled with sand and gravel that
may contain gold. The pan is submerged in water and shaken,
sorting the gold from the gravel and other material. As
gold is much denser than rock, it quickly settles to the
bottom of the pan. The panning material is usually removed
from stream beds, often at the inside turn in the stream,
or resting on the bedrock bed of the stream, where the
density of gold allows it to concentrate. This type of
gold found in streams or dry streams are called placer
deposits... |
