Overview

Metallurgical-grade fluorspar with CaF₂ content ranging from 60% to 90% is extracted and processed from the Kouh Sefid mine in Iran.

This grade is widely used as a flux in steelmaking, cast iron production, and non-ferrous metal smelting. By lowering the melting temperature, improving slag fluidity, and facilitating impurity removal, it plays a critical role in enhancing both process efficiency and final metal quality.

The product is offered in two main specifications:

FS-70/80
Purity: 70–80% CaF₂
Particle Size: 10–80 mm (Lump)

FS-80/90
Purity: 80–90% CaF₂
Available in two particle size options:
• 100–150 mesh (Powder)
• 10–80 mm (Lump)

Both grades are produced in accordance with international Metspar standards and are available for domestic supply and export markets.
