Gravity separation is an industrial method of separating two components either a suspension or dry granular mixture where separating the components with gravity is sufficiently practical ie the components of the mixture have different specific weight All of the gravitational methods are common in the sense that they all use gravity as the dominant force

Gravity separation uses differences in specific gravity (SG) between various minerals to achieve a separation and is normally a wet process although examples of dry gravity separators exist Gravity separation works best when there is a large difference in the SG in the minerals to be separated and the particle size is similar and not
