Particles of ore suspended in water are to be separated by elutriation. A small test rig comprising a vertically mounted cylinder with an internal diameter of 5 cm is to be used to determine the effectiveness of separation in which a flow of particle-bearing water is continuously fed. For a rate of flow to the elutriator of 300 mL min–1, determine the effectiveness of the elutriator in terms of particle sizes that can be separated and retained.
