In Our Society: The Economic Importance of Fluorite. The name ‘fluorite’ comes from the Latin word ‘fluere’ that means “to flow.”. Fluorite melts easily and is used as a flux in the smelting of metallic ores. A ‘flux’ is a material used to help remove impurities from ore as it is refined into metal. Physical properties include crystal habit, cleavage, fracture, luster, color, streak, hardness, specific gravity, magnetism, luminescence, radioactivity, optical properties, fluorescence, and taste.
