ABSTRACT:
A precious metal recovery bowl includes a steep peripheral wall, a floor having an upward and inward shape at a relatively low angle, a centralized frusto-conical member having a moderately steep slope and a top central ring with a vertical outer wall terminating in a circular lip and encompassing a central, vertical, overflow channel. A tangential, horizontal nozzle extending through the peripheral wall is connected to a hose which supplies water to the bowl so as to separate a pre-screened mixture of tailings and precious metals located in the bowl.
