Alluvial Placer Gold Deposits. Definition: Alluvial deposits are the most common type of placer gold deposit.

These are older river or streambeds which formed on the elevated side slopes of drainage ...

All placer deposits have concentrated gold from its source in some kind of trap. The vast majority of the placer gold that is mined in the world is of the alluvial variety. Alluvial placer deposits are formed in watercourses such as creeks, rivers, streams and deltas.

The fineness of placer gold varies greatly and has been studied by many investigators. A survey of the literature indicates that for most placer deposits the fineness ranges from 500 to 999, that is from electrum to nearly pure metal; most of placer gold is above 850 fine. The other elements in placer gold are mainly silver, copper and iron.

The IGR 3000 Gold Washplant was designed for a nominal 30 tons/hour feed rate based on an alluvial type material with moderate clay contamination. Material is loaded into the plant feed hopper through a static scalping grizzly with 75 mm bar spacing. Oversize is to be periodically removed manually from the grizzly. Undersize feed material is washed into the scrubber feed chute by water jets ...

Alluvial gold deposits. Normal alluvial placer deposits form by the power of flowing water washing away lighter materials and gravels and leaving behind heavier material such as gold— very similar to what happens in a sluice box when the flow of water washes away the lighter materials and the gold is deposited in the riffles.

Placer Gold Mining. Placer gold mining mainly refers to mined from the land surface or river or underground.

Other articles where Eluvial placer is discussed: placer deposit: Eluvial placers form on hillslopes from weathered deposits. They are not acted on by streams but by rainfall and wind, which carry away the light materials; thus they may be considered intermediate in the formation of stream placers.

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

Placer gold (alluvial gold) recovery process is to extract gold and associated minerals from placer ore by gravity separation. The processing equipment includes rotary screen, spiral washer, chute, mineral jig, shaking table, etc. In recent years, centrifugal concentrator is widely used.
