• Hydrofluoric acid production — Fluorspar plays a vital role in hydrofluoric acid production, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Aluminum smelting — Fluorspar plays a vital role in aluminum smelting, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Cement production — Fluorspar plays a vital role in cement production, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.
• Refrigerant manufacturing — Fluorspar plays a vital role in refrigerant manufacturing, where its unique physical and chemical properties provide performance advantages that are difficult to replicate with alternative materials.

Sector Breakdown

The largest consuming sector for Fluorspar is steelmaking flux, which accounts for a substantial share of global demand. The second most significant application is hydrofluoric acid production, which has shown strong growth in recent years driven by technology adoption and regulatory requirements. Emerging applications across clean energy, defense, and advanced manufacturing are expected to expand the demand profile for Fluorspar in the coming decade.

Demand Outlook

With a criticality level of medium and a supply risk rating of medium, the demand trajectory for Fluorspar is closely monitored by governments and industry analysts. Its inclusion on the USGS critical minerals list underscores the strategic importance of securing stable supply for domestic industries. The European Union has similarly recognized its importance through inclusion on the EU Critical Raw Materials list. Growing demand from electrification, digitalization, and defense modernization programs is expected to place additional pressure on existing supply chains.
