The origin of that gold we still haven’t put our finger on but it’s possible that that gold has been recycled from weathering of previously existing conglomerates or carbonaceous beds that no longer exist In their present form it’s alluvial gold but it’s ultimate origin is still in questionDec 06 32 Land use Diamond washing plant is used for extraction of diamond and gemston It is mainly used for Alluvial or It is produced by Qingzhou Yongli Mining and Dredging Machinery Co

bulk sampling Abstract Bulk testing of an area including old alluvial gold diggings on the flanks of Mount Tymn indicates a resource of about 30 000 cubic metres from which a minimal grade of 044 g/cubic metre is revoverable by gravity and a potential resource of 260 000 tonnes from which 086 g/t gold may be recoverable by cyanidationMethod of placer gold deposits exploration Develop a database that describes the individual weights of the gold grains to provide the sampling parameters for each of the definable

To explore an alluvial placer deposit costs much less than to explore a primary deposit A cased drill sampling is guided by a refraction seismic study to limit sampling to the most significant places and to limit initial exploration expens The gold or diamond alluvial placer deposits are controlled by a May 07 32 The point of sampling is to find out were the gold has traveled and dropped out of the faster current the best way to figure this out is to be able to watch a river in flood but be careful and see where and how the high and low pressure zones form and what causes them main current flow eddies broadening of the river obstructions

The sampling and the estimation of the gold present and recoverable play a very important part in the history and development of all placer deposits For this reason everyone interested in placer mining should know the best methods of working this class of mineral depositSampling placer deposits is a little different from sampling a lode or vein deposit because of the nature of a placer deposit It is not a solid rock but a sandy or gravelly material and can be spread over a wide area The basic principals of sampling still apply though First one must have a basic plan
