Abstract
A method of separating particles into two groups of different densities consists of suspending the particles in a bath containing two non-miscible liquids of different densitiesmoving in two streams in opposite directions. The specific gravity of the denser liq. is greater than that of the denser solid and the specific gravity of the less dense liq. is less than that of less dense solid. Typically the liquids are water and mercury.
