ABSTRACT:
A gold concentrator comprises a housing at the end of a sluice into which a quantity of sand, rock and gold particles is deposited. A screen on a portion of the sluice serves to segregate larger particles of rock and gold from the finer sand particles. A hose is attached to the rear wall of the housing and water under pressure mixes with the finer sand. The mixture of sand and water strikes a wall and a depending flange within the housing causing the mixture to turn over therein thus creating a suspension of particles within the liquid. The suspension falls onto the sluice and flows downwardly therealong and over the screen at the bottom thereof. A flange at the end of the sluice turns the suspension in the opposite direction where it flows down a forwardly extending second sluice. The forwardly extending second sluice has a rubber mat thereon having a series of transversely extending grooves which function to trap the gold and black sand particles therein. The screen serves to retard the flow of suspension mixture as it advances down the sluice and to remove large particles of rock, gold and silver in the suspension.
