Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm. Gold occurs predominantly in native form in silicate veins, alluvial and placer deposits or encapsulated in sulfides. The recovery of gold from gold-bearing ores depends largely on the nature of the deposit.

A prospector hunting for a gold placer follows up the water channels in which he finds specimens of all the rocks in the neighborhood. In Australia, the prospector looks amongst these to find samples of granitic, porphyritic and quartzose rocks or clay-slate as likely signs, and also pieces of quartz honey-combed and rusty, which we have described before as "float or blossom."

Jan 25, 2008· The gold floats because of the surface tension of the water. In a small recirculating operation you can use a Jet Dry or dish soap to break the surface tension and the gold will not float anymore. With a dredge as long as you don't bring the gold to the surface it shouldn't float. Maybe a deflector to keep it down in the sluice might help. Good ...
Thorndike/Barnhart's Advanced Dictionary defines "placer" as "A deposit of sand, gravel or earth in the bed of a stream containing particles of gold or other valuable mineral."
