Gold prospecting in beach is an accumulation of valuable minerals formed by gravity separation during sedimentary processes and in geology called placer deposits . Beach placers form on seashores where wave action and shore currents shift materials, the lighter more rapidly than the heavier, thus concentrating gold .
Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite.
Among the examples of beach placers are the gold deposits of Nome, Alaska; the zircon sands of Brazil and Australia; the black sands (magnetite) of Oregon and California; and the diamond-bearing marine gravels of Namaqualand, South Africa.
On the Pacific shores of Canada and America, extending in patches for a considerable distance from southern California to Alaska and the Bering Sea, are a number of auriferous deposits, known as "ocean-placers." Similar formations exist also in New Zealand and elsewhere.
To find Gold prospecting in beach at a given area several factors must combine to allow it to form. (these factors are not 100% foolproof but these are the basic signs that beach placer gold may occur in the area)
At the area to be tested womb gold prospecting in beach, around location beach it should have a gold content, whether it's a gold mine or a hill containing gold, Because the gold (usually flour gold) leaves the river heading to the beach area because the local sea and wave conditions will allow the formation of a beach placer. And the local geography allows the beach placer to form Gold prospecting in beach as a result settle to the Sea floor a short distance from the mouth of the river.
The existence of a gold bearing beach placer can be seen if you take a section through the sands. Sometimes a visible line of black sands can be seen at different intervals through the section, and the only real way for us to know whether the gold prospect in beach area, we also have to analyze the way panning process with gold panning equipment
Fresh survey has to be made each day before commencing operations, because at low water on the beach the position of the sands is liable to be changed at every tide.
Gold panning is a simple process. It is based on the fact that heavier material will sink to a lower level than lighter materials. When a variety of materials such as dirt and stones, and gold are suspended in moving water the heavier material with a higher specific gravity will settle first on the base
