Abstract
Abstract A density separation jig that combines vertical and horizontal liquid force components to separate the end product at the center of the grid. The frequency of the diaphragm is controlled to produce the horizontal force component and establish maximum separation. The grid can comprise various zones of mesh to take advantage of the horizontal separation. The discharge chute can be transparent and the jig components designed for easy portability.
