Two non-metallic industrial minerals — barite for oil & gas drilling muds, fluorspar for hydrogen fluoride and semiconductor etching.
Barite: Barite is irreplaceable in oil and gas drilling — no substitute matches its combination of high density, chemical inertness, and low cost as a drilling fluid weighting agent.
Fluorspar: Fluorspar is the source of all commercially produced fluorine. It is essential for semiconductor manufacturing and refrigerant production, with China controlling over 60% of global output.
Barite: Barite (barium sulfate, BaSO₄) is a dense, non-metallic industrial mineral essential to the global oil and gas industry. Its exceptionally high specific gravity makes it the primary weighting agent in drilling fluids used to control wellbore pressure and prevent blowouts. Fluorspar: Fluorspar (calcium fluoride, CaF₂) is a mineral used to produce hydrogen fluoride, which is the precursor to fluoropolymers like Teflon and to the hydrofluoric acid used in semiconductor manufacturing.
As tracked by Critical Minerals HQ, Barite is currently $165 USD/t and Fluorspar is $380 USD/t. The two minerals are quoted in different units (USD/t vs USD/t), so see the live price panels above for the most recent figures.
Neither is "better" in absolute terms — each is engineered for different end-uses. Barite is primarily used for: Oil and gas drilling fluids (weighting agent), Medical imaging (barium contrast media for X-rays and CT scans), Paints, coatings, and plastics filler, Rubber and ceramics manufacturing. Fluorspar is primarily used for: Hydrogen fluoride production for fluorochemicals, Aluminum and steel production fluxes, Semiconductor manufacturing (HF acid etching), Fluoropolymer production (Teflon, refrigerants). The right mineral depends on the application.
Barite and Fluorspar are quoted in different units (USD/t vs USD/t), so a direct numeric rarity comparison from spot price alone is indicative only. See the indexed 25-year chart on the live page for relative scarcity behavior.
Specific US import-reliance percentages are not in our on-file reference text for either Barite or Fluorspar. See the official USGS Mineral Commodity Summaries for the latest figures.
Barite top producers (USGS): China, India, Morocco, Mexico. Fluorspar top producers: China, Mexico, South Africa, Mongolia. The mineral whose first-listed producer accounts for a larger share of global output carries the greater supply-chain concentration risk.
