When used in lignite removal applications, Flat Bottom Classifiers are able to separate the lightweight lignite from the heavier sand particles. Lignite has a specific gravity, or relative density, of about 1.3, compared to the specific gravity of sand, which is generally 2.7. The separation occurs because of this difference in specific gravity.
