Abstract. As a rare and non-renewable strategic non-metallic mineral resource, fluorite has been widely used in many fields such as national defense, chemical industry, metallurgy, optics. Fluorite resource reserves are abundant in China, but there are many lean ores with complex composition and low recovery. This study summarizes the reserves ...

When gravity separates fluorite ore and scheelite, the difference in specific gravity between the two minerals must be considered. Fluorite has a relatively low specific gravity of about 3.2-3.3, while scheelite has a higher specific gravity of 5.9 to 6.1. This significant difference allows efficient separation using jig separators, shaking ...
