Applications of metallurgical grade Calcium Fluoride (Flurospar) lumps

Metallurgical grade calcium fluoride, commonly known as fluorspar, is a crucial material in various industrial processes due to its unique properties and versatility. At SARSA Minerals, we supply high-quality metallurgical grade calcium fluoride with a purity range of 70-85%, catering to diverse industrial needs. Here are the key applications of our metallurgical grade calcium fluoride:

1. Steel Manufacturing

Calcium fluoride is widely used in the steel industry as a flux to facilitate the removal of impurities and improve the efficiency of the steelmaking process. Applications include:

• Blast Furnace Operations: It lowers the melting point of raw materials, enhancing slag fluidity and reducing energy consumption.
• Electric Arc Furnaces (EAF): Improves the refining process by aiding in the removal of sulfur and phosphorus from molten steel.
• Continuous Casting: Enhances the quality of steel by reducing viscosity and promoting smooth slag formation.

2. Aluminum Production

In the aluminum industry, calcium fluoride plays a vital role in the smelting process. Applications include:

• Electrolytic Reduction of Aluminum: Used as a flux to lower the melting point of alumina and improve the efficiency of the electrolytic process.
• Aluminum Refining: Assists in the removal of impurities and enhances the quality of the final aluminum product.

3. Cement and Glass Industries

Calcium fluoride is used as a fluxing agent in the production of cement and glass. Applications include:

• Cement Manufacturing: Improves the burnability of clinker, reduces the melting temperature, and enhances the quality of the final cement product.
• Glass Production: Acts as a flux to lower the melting point of raw materials, improving the efficiency of the glass melting process and enhancing the properties of the glass.

4. Ceramics and Enamel

Calcium fluoride is used in the ceramics and enamel industries to improve the properties and performance of the final products. Applications include:

• Ceramic Glazes: Enhances the smoothness and durability of ceramic glazes, improving the appearance and longevity of ceramic products.
• Enamel Coatings: Used in enamel formulations to improve adhesion, reduce melting temperatures, and enhance the quality of the enamel coating.

5. Chemical Industry

In the chemical industry, calcium fluoride is used as a raw material for producing various fluorine-containing chemicals. Applications include:

• Hydrofluoric Acid (HF) Production: Calcium fluoride is a primary raw material for producing hydrofluoric acid, which is essential in the manufacturing of fluorocarbons, fluoropolymers, and other fluorine-based chemicals.
• Fluorine Gas Production: Used in the production of elemental fluorine, which is utilized in various industrial and commercial applications.

6. Welding and Brazing

Calcium fluoride is used in welding and brazing fluxes to improve the quality and performance of welded joints. Applications include:

• Welding Rod Coatings: Enhances the stability of the arc, reduces spatter, and improves slag removal.
• Brazing Fluxes: Lowers the melting point of filler metals, improves wetting, and enhances the strength and quality of brazed joints.
