Separations by density, such as the separation of non-ferrous scrap into light and heavy alloys, are often realized by means of heavy media. In principle, kinetic gravity separations in water can be faster and cheaper, because they do not rely on suspensions or salt solutions of which the density must be tightly controlled. Test results of a prototype kinetic gravity separator in combination with suitable size classification techniques show promising results for particle sizes between 2 and 10 mm.
