Claims
- 1. An apparatus for stratifying ore in particulate form suspended in a solution in accordance with the density of the ore particles and for washing the crude ore particles, such apparatus having a working cell for receiving a solution having ore particles to be treated, the improvement which comprises a gas cell disposed at least partially below said working cell, partition wall means separating the working cell and the gas cell and having at least one horizontal aperture therein for providing vertical communication between the working cell and the gas cell, a valve associated with the partition wall means and having a valve element disposed above the aperture and normally urged into a closed position by the weight of the liquid in the working cell when the solution having ore particles to be treated is introduced into the working cell, means for introducing a pressurized gas into said gas cell to urge said valve element against the force of the liquid to open said valve against the force of the liquid until sufficient gas pressure escapes into the working cell to cause the weight of the liquid to again close the valve, thereby producing a repetitive vibration of the valve element and a corresponding repetitive pressure surge within the liquid in the working cell, at least one inclined sieve mounted in the working cell above the valve, means for feeding particulate ore onto the sieve, and means for discharging stratified ore particles.
