Uses & Applications

Applications and End-Uses for Fluorspar

Fluorspar (CaF2) is a medium-criticality industrial mineral with annual global production of approximately 8.5 million tonnes. Fluorspar, or calcium fluoride, is the primary source of fluorine for industrial use. It is essential in steelmaking as a flux to lower melting points and in the production of hydrofluoric acid used across the chemical industry. Fluorspar is also critical for manufacturing refrigerants, fluoropolymers like PTFE, and uranium fuel processing.

Key Applications

The primary end-uses of Fluorspar span multiple sectors. The following applications represent the most significant sources of global demand:

• Steelmaking flux - Key alternatives include Limestone, alumina, other fluxes. Fluorspar is the most effective flux for lowering slag viscosity but can be partially replaced at some efficiency cost
• Hydrofluoric acid production - Fluorspar is valued in hydrofluoric acid production for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Aluminum smelting - Fluorspar is valued in aluminum smelting for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Cement production - Fluorspar is valued in cement production for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Refrigerant manufacturing - Key alternatives include Hydrocarbons, CO2, ammonia (natural refrigerants). F-gas phase-down regulations (Kigali Amendment) are reducing fluorocarbon refrigerant demand, but HFOs (next-gen refrigerants) still require fluorine

Product Forms and Specifications

Fluorspar is commercially available in 4 primary product forms, each serving different industrial requirements:

Demand Outlook

Fluorspar appears on both the USGS Critical Minerals List and the EU Critical Raw Materials List, underscoring its strategic importance across Western economies. Growing demand from electrification, digitalization, and defense modernization is expected to place additional pressure on the Fluorspar supply chain through the end of this decade.
