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. As such, large amounts of fluorite are extensively used in open-hearth steel and steel enamelware production, the smelting of aluminum, as well as lead and antimony refining.

In general, precipitated calcium carbonate (PCC) is used as a mineral filler in paper industries; while natural calcite (CaCO 3) ore is also suitable for industrial use if it is a finely ground high-grade material.Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth's crust.
Batch flotation tests on a run-of-mine fluorite–calcite ore indicated that, using this reagent schedule, the calcite removal rate could reach above 85% while fluorite has a loss rate of below 11%. The novel reagent schedule of "CA + NaF + SOA" exhibits great potential for industrial application in the flotation of fluorite–calcite ore.
