Alluvial gold processing plant - China Mining Equipment Supplier
“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 most cost-effective choice for miners now.
Jig Or Centrifuge For Flour Gold Project? - ICMJ's Mining

What alluvial gold mining?? and what is deep reef mining
Sep 01, 2009 · Alluvial mining is extraction of gold from soil, usually from a river bed. This is typically done by digging the soil from trap locations and panning it to recover gold concentrate. This concentrate is then mixed with mercury that amalgamates the gold and then the gold is recovered by burning the mercury.
Alluvial and Placer Mineral Deposits | Geology for Investors
Feb 21, 2020 · Gold, particularly, has often not moved far, so a minor alluvial gold deposit can result in a major underground gold mine as in Australia’s Kalgoorlie or Bendigo gold rushes. In other places, most of the gold was in the alluvial deposits as in the Klondike/Alaska Gold Rush and the California gold rushes of the 19th century.
