Gold Mining Plant is mainly mined from land surface or river or underground. Has various types of gold raw material: alluvial gold/placer gold/sand gold/river gold/ gold tailing, etc. The main process includes feeding, washing, sieving, rough separation, final concentration, and refining.

For fine gold recovery the use of riffles can actually be a negative design element and most boxes specifically built for this type of gold don't use any type of riffle system. Good examples of this box type are the 'DFS' (Damn Fine Sluice) and Steve Gaber's 'Pop-and-Son Sluice'.

The Bulolo gold placer in Papua New Guinea is an example of Cainozoic gold placers of deltaic origin. Prior to faulting in the Bulolo Valley, Papua New Guinea and damming of the Bulolo Valley, gold-bearing tributaries of the Bulolo River included Big Wau Creek, Koranga and Namie Creeks and Edie Creek. The formation of a lake created lacustrine deltaic conditions, which led to formation of the ...

Sluice boxes are often used in the recovery of black sands, gold, and other minerals from placer deposits during placer mining operations. They may be small-scale, as used in prospecting, or much larger, as in commercial operations, where the material is first screened using a trommel or screening plant. Typical sluices have transverse riffles over a carpet, which trap the heavy minerals ...
