Abstract
An elutriation apparatus has a mechanism adapted to move water along a path, the water entraining material particles of different density, and a plurality of elutriation columns interfaced to the mechanism adapted to move the water with entrained particles, the elutriation columns interfaced along the path, each elutriation column having a vertical bore with water controlled to travel up the vertical bore at one velocity and having also a capture element at the bottom of the bore. As the water with entrained particles passes over each interface to an elutriation column along the path, particles of a density sufficient for the particles to settle in the elutriation column at a velocity greater than the upward velocity of water in the bore of the elutriation column, settle to the bottom of the column, and particles of lesser density pass on to a next elutriation column interfaced along the path.
