Function: This type of equipment is designed for small-scale gold prospecting and mining operations, typically used to separate gold from alluvial deposits like river sand and gravel.
Mechanism: It uses a gasoline engine to power a water pump, which washes material over a sieve or trommel screen to separate heavier gold particles from lighter materials using gravity separation principles.
Portability: Its compact and lightweight design makes it easy to transport and operate in remote locations
