An efficient Gold Wash Plant's recovery process of Gold from an Alluvial/Placer deposit should include the following crucial steps: Ore Feed. Sizing (screening and classifying). Concentration and recovery of coarse Gold (nuggets). Concentration and recovery of fine Gold. Final concentrate cleanup and smelting of the Gold.
Because gold is heavier than most of the material moved by a creek or river, it can become concentrated in hollows and trapped in the bed of the river. These are known as secondary (alluvial) gold deposits and they can be worked using a gold pan or cradle. Alluvial gold deposits sparked the Australian gold rushes of the 1850's. Resources
