“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 alluvialsoil gold is using gravity separation method which is most costeffective choice for miners now How it looks like
Alluvium from the Latin alluvius from alluere to wash against is loose unconsolidated not cemented together into a solid rock soil or sediment that has been eroded reshaped by water in some form and redeposited in a nonmarine setting Alluvium is typically made up of a variety of materials including fine particles of silt and clay and larger particles of sand and gravel
The gold was concentrated by washing away the lighter river sands with water leaving behind the dense gold particles which could then be further concentrated by melting By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed The mining of alluvial deposits and later lode or vein deposits required crushing prior to gold extraction and this consumed immense
