In most gold bearing veins, the gold does not form into well-developed crystals. Unlike quartz which often forms good crystals, gold requires a very specific set of circumstances to grow into good crystal shapes. Few gold deposits produce good crystal specimens, as most gold forms naturally as irregular masses and lumps.

How to Find Gold in Clay Sand: Methods for Panning in Rivers. –gold is more than three times heavier than the black sand it is found with –gold "falls out" after swift water has slowed down –gold works its way down through the overburden, and it is always close to bedrock.
– Processing of auriferous sand on dredges. Large structures treated sand containing gold. In this year the construction processes about a million tons of sand .

Jan 29, 2014If your assay shows values for gold at almost 13 Troy oz./ton, there would be, assuming a specific gravity for magnetite (black sand) of 5.0, roughly 64 Troy oz./ cu. yard of black sand. IF there is a layer of clay below your placer, it will catch all of the migrating gold in a layer approximately a few millimetres thick on the clay's surface.
03.05.2010Motherlode produces some extremly hi karat gold from slate in many colors. Merced River is a perfect example.

I used my Bazooka Gold Trap in Kaufman Creek. I dug one hole along the bank down to a blue clay layer. I only ran about 6 quarter full buckets of unclassified material. I got fine gold and a bunch of black sand. It was a fair rate of recovery for only a short time in an area where I have never prospected and had very little knowledge.

Feb 03, 2009Gold is very dense and never rusts, as the surrounding rock is weathered, tuned to clay and sand, it liberates gold. The gold tends to stick around due to its density, so it can accumulate in highly weathered soils above gold bearing quartz veins. The soils end up with a higher concentration than the original quartz veins.

Stop the rotation. If you are lucky, you will see a few flecks of gold in the dark material that remains in the bottom of the pan. Carefully drain out water and let the black sand and gold dry. Lift out most of the black sand with a magnet, and separate that gold from the remainder of the sediment with tweezers. Where to Pan on Federal Land

Placer deposits are created when gold is weathered out of rock over the aeons and moved by flowing creek water. These small particles and nuggets of gold are slowly transported down a creek or stream, and accumulate in the sand in banks, along the shore, and in rock crevices.
Gold has been discovered in nearly every state in the U.S. The famous gold areas of Alaska, California, and many of the western states still produce lots of gold, and even many of the states across the Midwest and east coast have gold that can be recovered by prospecting.

If you only have a few cups of gold baring material, you can simply use a small gold finishing pan and a magnet. One annoyance you will most certainly encounter when finishing the gold extraction process is black sands. Black sand, or iron sand, is a magnetic sand that is very heavy.
How gold is made - history, used, parts, procedure In dredging, buckets on a conveyor line scoop sand, gravel, and gold ore from the bottom of streams. In power shoveling, huge machines act like shovels and scoop up large quantities of gold-bearing sand and gravel from stream beds.
Buried gold placer deposits form in deep valleys which in ancient times would have had gold bearing streams or rivers occupying them. Over times these valleys have become filled by layers of clay, gravel and sand which can be hundreds of feet in depth. The other way that these deposits form is
