Alluvial Gold Washing

The best-known of the exogenetic ores is alluvial gold which also called placer gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains. Alluvial gold deposits are formed through the weathering actions of wind, rain, and temperature change on rocks containing gold. Under this circumstance, the most efficient way is gravity processing to extract the placer gold by washing away the mud and sieve out the big size stone.
