Sink-Float Tests are classed as bulk or selective separations. A bulk test gives two products, first, the lighter minerals with a gravity less than 2.8 to 3.3 and, second, minerals having a gravity heavier than 2.8 to 3.3. The separation depends on the gravity of the media used. The heavy media generally used are as follows:
