Alluvial gold refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold. Best way to extract such alluvial/soil gold is using gravity separation method, which is
For the carbon in pulp method, the ground ore is mixed with water before cyanide is added. Then carbon is added to bond with the gold. The carbon gold particles are put into a caustic carbon solution, separating out the gold. In heap leaching, the ore is placed on open air pads and the cyanide sprayed over it, taking several weeks to leach down to an impervious base. The solution then pours
By 3000 bc gold rings were used as a method of payment. Until the time of Christ, Egypt remained the centre of gold production. Gold was, however, also found in India, Ireland, Gaul, and the Iberian Peninsula. With the exception of coinage, virtually all uses of the metal were decorativee.g., for weapons, goblets, jewelry, and statuary.
Gold panning is themon method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.

Gravity separation is an ancient and themonly used gold enrichment method. Placer gold is usually showed a single native gold in the form, whose particle size is generally greater than 16 t/m3 having big density contrast with gangue. So the gravity separation is the most important method for placer gold beneficiation.

History. The smelting of gold began sometime around 6000 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons 1997 mercury was first in use for extraction at about 1000 BC, according to Meech and others 1998, mercury was used in obtaining gold
Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.
By 3000 bc gold rings were used as a method of payment. Until the time of Christ, Egypt remained the centre of gold production.
