| 摘要 |
An improved process and apparatus for separating particulate solids based on differences in their specific gravities through agitation in alternating upward and downward water/liquid currents generated by discharges from a water/liquid column of fluctuating height, stored in a water/liquid holding tank connected laterally to and/or above the pulse chamber of a separation jig, wherein the intensity of the discharges and the upward and downward currents thus created are a function of the height of the water/liquid column, which is in turn responsive to the condition and composition of the body of particulate solids undergoing separation.
