What Is Alluvium?

Aug 28, 2017As rivers deposit alluvium, a gravity separation process occurs, which allows these denser valuable minerals to be deposited at certain points as well. Placer deposits are most commonly found at the bottom of waterfalls or along bends in the river, where the water slows down just enough to drop these metals and stones.

gravity separation: fl knelson concentrator " The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ores, especially smaller high value deposits.

Methods of Gold Mining

Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Panning Gold panning is mostly a manual technique of separating gold from other materials.

Alluvial Deposit

1.2.1.1 Alluvial deposits (river beds) Soils deposited in riverbeds are known as alluvial deposits. Some textbooks use the word 'fluvial deposits' for the same thing. The size of particles deposited in riverbeds depends on the speed of flow. If the flow of a river is strong, only large cobble-type material can get deposited.
