ABSTRACT An apparatus for separating particulate solids according to differences in their specific gravities through the use of water generated pulsation cycles, comprising at least one separation cell having a pulse chamber with a means for receiving water and generating a water pulsation, a water chamber for transferring the generated water pulsation, a perforated screen support for supporting particulate solids, and a separation chamber for separating the particulate solids according to differences in their specific gravities, wherein the pulse chamber, the water chamber, and the separation chamber are in fluid communication with one another through the perforations of the perforated screen support; means for feeding the particulate solids to be separated onto the perforated screen support; at least one water holding means extending laterally of and above the pulse chamber, wherein the water holding means stores unused water accumulated from previous pulsation cycles and water supplied at a preset rate from a water supply means to produce a water column possessing a gravitational pressure head; an inflow means connected between the water holding means and the pulse chamber for permitting the inflow of the stored water from the water holding means into the pulse chamber of the separation cell, wherein when the inflow means is in an open position, the water holding means is in fluid communication with the pulse chamber, thereby allowing for the stored water from the water holding means to enter into the pulse chamber to produce a water pulsion in the separation cell whenever the gravitational pressure head of the stored water from the water holding means is sufficient to overcome the resistance of the particulate solids supported on the screen support; an outflow means connected laterally of or below the pulse chamber of the separation cell for permitting the outflow of water from the separation cell, wherein, the outflow means is regulated alternatively to the inflow means to produce water pulsations in the separation cell; and, means for removing the separated solids produced by the water pulsations from the separation cell.
