Overall, this Special Publication provides a comprehensive collection of contributions that address fundamental questions in interpreting observations of gold particle heterogeneity and compositional ...

Naturally occurring gold mainly falls into two basic categories - placer (alluvial) and mountainous (eluvial). Thus natural gold is mainly found in mountainous regions or near streams where water has "washed" gold from the mountains and scattered it in alluvial deposits downstream. These sandy areas of gold, called alluvial or placer …

The term 'Alluvial' is used to describe: A deposition of sediment over a long period of time by a river; an alluvial layer. Or, to put it in simple terms, river mud. Now, on the face of it, this 'offer' looks quite attractive. 450kg of 22ct gold, albeit in 'dust' form, would be worth somewhere in the region of £10.5 million.

Alluvial gold usually takes the form of dust, thin flakes or nuggets. Initially the dredged river bed material is separated from the small sand faction where the gold is found. Physical separation methods like screening and gravity separation are used to separate the gold from the mineral fraction. This method of mining is an environmentally ...
