Gravity Separation Dense media separation or jigging is often used for the gravity concentration of fluorite ore. In dense media separation, the crushed ore is suspended in a medium with a specific gravity between fluorite and the gangue minerals. The heavier fluorite particles sink, while the lighter gangue particles float.
